Keep working during TFS Side-by-side upgrade - tfs

I know someone answered this question here
but there is only one answer and no feedback from the author. I'd like to have more sources before starting my upgrade.
So, we're planning on upgrading TFS 2010 to TFS 2018 but we need to keep working while doing so.
Is it possible to have on going modifications while upgrading to TFS 2018 and commit them when the upgrade is done ?
Thanks in advance

It depends on what you mean by "working". If you're talking about source control, then yes, the answer to the other question is accurate. If you're talking about work item changes, builds, etc, then the answer is "no".
When doing upgrades on TFS instances considered critical for business, the best process to use is this:
Do a test upgrade first, leaving the existing instance online.
Fix any problems that you discover that occur post-migration and, if necessary, write scripts to quickly apply the fixes
Re-test the upgrade process, including applying your fixes
Do the final upgrade over a weekend or overnight, outside of normal business hours

TFS 2015 to TFS 2017 migration advices

What would you recommend or what is the official recommendation of Microsoft regarding migration path after pre-production (test) upgrade?
is it to do an In-Place Upgrade? or is it to do a database migration to a new hardware? Need this information for one of my customers.
The second question is, let's say I choose the second approach and make a production upgrade moving the databases to new hard, do I have a rollback if something goes wrong? or the old environment becomes unusable once I make a production upgrade (remember I am using new hard/VMs)
Many thanks
Actually it's completely based on your requirements. If you want to use the old hardware then you can do In-Place upgrade, if your want to migrate to new hardware then just do the database migration.
In-Place upgrade:
Please note that you cannot simply rollback for In-Place upgrade if something goes wrong. So backup the databases first.
Expect the best, prepare for the worst.
While we put a lot of effort into ensuring that TFS upgrades are
highly reliable, it always makes sense to prepare for the case where
something goes wrong. The single most important step you can take here
is to ensure you have a complete and consistent set of database
backups.
If you're upgrading in place (not moving to new hardware), consider
doing a dry run of your upgrade in a pre-production
environment.
Source here: Upgrade TFS.
You can reference this article to do the upgrade:
In-place upgrade to TFS 2017 RTW (Release To Web) with Reporting and SharePoint
Migrate to new hardware:
Migration will be more flexible and safe, the old environment will still available, it will not be affected if the migration failed. So in my opinion if you have new hardware, then it should be better to do the migration.
Please see Move or Clone Team Foundation Server from one hardware to another for details.
Please note that whether it is in-place or migration, it must match the Requirements and compatibility first for each TFS version. And never forget to Backup the databases for both of them.

Migrate TFS Changesets

I assumed this would be easy, but I'm not finding anything on it...
I have a project in TFS 2010, which needs to be moved to a new TFS 2015 server. Apparently the project cannot simply be moved normally because it's using a different project template which is not compatible and causes errors when trying to migrate (so I'm told - I don't have any more details on this).
I'm looking for a way to bring over the changesets, keeping history, to the new server. I assumed there was some kind of "dump" where you could export the TFS changesets, then import them into the new server into an empty project - but I'm not finding that option.
TFS Integration is deprecated and apparently doesn't work for TFS2015, with no alternative listed.
I'm open to other creative options like temporarily exporting to a different version control system - for example, I've looked at SVNBridge, but I can't even get that working, let alone figure out if it would help here.
Is there a way to migrate all changesets for a given project and keep history, without migrating the entire project?
There is no default way to migrate changesets in TFS, you would need 3rd party tool, like OpsHub (some features are not free), to migrate the most commonly requested data. Check: http://www.opshub.com/products/opshub-visual-studio-migration-utility/
Or you may consider doing a upgrade from TFS 2010 to TFS 2015, which is a full data transfer. To understand factors that affect your upgrade's compexity, check the requirements and review the upgrade process.
Learn if a dry run makes sense for you, and weigh the benefits and the costs to perform a pre-production upgrade.
When you're ready to upgrade, minimize downtime with the TfsPreUpgrade tool - especially for very large TFS collection databases (> 1 TB). Follow these steps for how to upgrade TFS.

Work Items were lost during TFS upgrade

Last week I upgraded our TFS 2012 Server to TFS 2013. I read the MSDN documentation first and I also followed the documentation as I performed the upgrade. Everything seemed to go ok.
After the upgrade I ended up with 7 or so Team Projects that the wizard couldn't configure, for whatever reason, and needed manual configuration.
I noticed this week that ALL of the work items under one of my Team Projects are missing. Gone. Like even if I select Team|Go To Work Item and enter in a known Work Item Id, I receive an error that the item is either missing or I do not have permission to view it. I'm an Administrator on the TFS server and I'm the TFS Admin, so I highly doubt permissions are the issue.
I remoted into the server and launched SSMS to explore the raw data. I know for a fact Work Item 450 is missing (it's the only Id I remember at this point). I selected the TOP 1000 from WorkItemsAre, which seems to be the table that holds the Work Items (?). There is a gap in the Ids, I see 1-448, then the numbering picks up again at 457. So, somehow my Work Items appear to have been deleted. I stopped there, I assume there are more gaps since I'm missing more than 9 items.
Now I haven't gone through every one of our Team Projects. I've only touched 3 of them since the upgrade. Thankfully the largest, most active Team Project, with the most work items/version history seems to be intact. I'm not sure if any other Team Projects are missing their Work Items too.
Has anyone else experienced this? Does anyone know if there's some "secret squirrel" way to recover these missing work items, or have they been hard deleted and are gone for good (other than looking through tape backups of the server).
Any advice would be appreciated.
I already migrated to TFS 2013 from TFS 2012.
The problem of manual configuring the project may occur when you have customized work item types in TFS Project Templates. Did you customize your project templates?
Although, I can hardly believe that work-items getting hard deleted from TFS. This issue may occur probably because of archiving during migration. The workitems that TFS upgrade wizard may not have "understood" during migration/upgrade, might be archived and moved to another table in database Tfs_DefaultCollection.
You may want to consider that. I am not sure if that may be the case, but this happened when we migrated from TFS 2010 to TFS 2012 because we had many custom work items in TFS 2010. Hence we had to standardize templates before migration using powershell. But we lost some amount of history.
Hope that sparks some idea.

Team Foundation Build or TeamCity?

We are a mostly MS shop at work doing .NET LOB development. We also use MS Dynamics for our CRM app... all the devs are currently using VS/SQL Server 2008. We also use VSS, but everyone hates it at work and that is quickly on its way out.
We are begining our initiative for TDD implementation across the team (~dozen ppl). I've gotten TeamCity setup and have my first automated builds running succesfully using the 2008 sln builder and also using SVN that a co-worker had setup who is doing the source control analysis. When demoing to managament, I think they started to buy into my snake oil and threw out the suggestions of looking into TFS.
This threw a wrench in what I had planned for our TDD architecture; In a good way though, because I had always assumed that TFS was just too expensive and not worth it for our team (and i've seen the same in other shops i've worked at / know of). I do feel like MS is years behind in the TDD/CI area and that the third party products were probably much better and more mature... I still need to do a lot of research, but I figured I'd come here to see if anyone has actually used both systems.
I realize the TFS encompasses a lot more then just a build server... but I didn't want to make this too broad of a question at least on purpose. What are the practical pros/cons of using TFS/TFB instead of TeamCity - e.g. which benefits would we lose/gain? Has anyone here actually used both systems (TFS for TDD/CI and TeamCity/SVN) and can speak from practical standpoint?
I've done some searching on this topic, and one post I found here on SO mentioned that the cons of TFB was it only supported MSBuild. I was planning on using FinalBuilder with TeamCity; and it appears it also supports TFS as well...
Thanks for any advice
EDIT: Has anyone used TFS as their Build/CI server and can tell of success/failure stories?
We are a small development shop, and decided that Team Foundation Server carries too much overhead for us. We used to write custom MSBuild scripts to run from the command line, but after we discovered TeamCity, we moved our entire build process over to it.
We've found TeamCity to be easy to use and configure, and JetBrains provides excellent support and documentation. They are also on a much faster release and update cycle than Microsoft.
Their support for SVN source control is excellent, and we like the fact that they support both MSTest and NUnit for unit testing.
We also liked the fact that the TeamCity Professional edition was free, so we could evaluate it to see if it worked for us. We haven't hit the number of project configurations (20) that would require us to upgrade to the Enterprise edition.
This question has a lot of good answers about TeamCity. It does not compare to TFS but it might shed some light on TeamCity for you.
I have used both, and I have had success with both, but TeamCity was so much easier. TeamCity was a breeze to set up and configure. TFS was not. TeamCity is rock solid, it's easy to maintain and it just plain works. The developers at JetBrains have done a great job responding to the community. They get a release out every 6 to 8 months that adds real value. TFS is on a 2 year or more cycle.
TeamCity gives you more choice in how you build and what source control you use. It's not all in one, but that's sometimes a good thing. It's got a good set of extension points as well. We have also been really happy with the agent model it has.
I've gone through 3 absolutely painles upgrades in TeamCity. The one TFS upgrade we did took our build and source control down for 3 days. I'm the admin for TeamCity on our project and it takes up a couple of hours a month. TFS took a couple of days a week.
TeamCity + SVN + VisualSVN has been the smoothest environment I have ever worked in. TFS was generally smooth on the day to day, but only if someone was there keeping it running.
Hope that helps
The benefits of TFS are one integrated environment that is supported by Microsoft. I personally do not like TFS for source control and have had a number of issues with it. It is clunky, however it had the benefit of having VS integration (which is also available in VisualSVN, but is not as robust).
Personally, I think you would be much better off using SVN/TeamCity. It is just easier to work with and behaves more as you would expect. As with most open source software, both are constantly evolving and will always have the latest and greatest feature before Microsoft. The integration between the 2 is really good and I have found no fatal flaws in the system. I constantly push to go this route in my current company (we use TFS), as I believe it is a much better workflow. As an added benefit, it is significantly cheaper than going the TFS route.
I have also used FinalBuilder with TFS - my question there is what are you really buying with FinalBuilder that you can't do with NANT/MSBuild? The answer at my shop is unfortunately very little IMO.
First off, see this post:
SVN vs. Team Foundation Server
As to your question about which environment better fosters TDD and such, my two cents is that the build management system matters much less than what's in the build file itself. Your Ant or MSBuild file should have the targets that do your testing. With MSBuild or Ant, you don't have to use MS's test suite. You can still use nUnit or whatever else you want. That means it doesn't matter if TFS is calling your MSBuild file, or if CruiseControl is, or if TeamCity is. The smarts are all in the build file and the tools you integrate with it.
My personal choice is not to get locked down into TFS's way of doing things, since you have a lot more freedom for a lot less cost with the wealth open-source testing tools that are out there. TFS is about to receive a major upgrade, as well. If you are going to go with TFS, my advice is to at least wait until 2010 is released. Concentrate on making your MSBuild files as good as they can be right now.
That being said, I must admit that TFS has one of the nicest build systems out there (2005 was terrible, 2008 was nice). Being able to easily customize notifications and the release process all inside .NET code was pretty cool -- you had a lot more central control over build and release policy than we did with CruiseControl.NET.
So I've used TFS and SVN/CCNet. I can't speak much to TeamCity. But IMO a build management system should be fairly agnostic to what is being built and how it's being built. For us, the extra control in the release management process that TFS brought us just wasn't enough of a bonus for us to justify the greatly increased administrative effort of a fully integrated TFS solution. Nor was it enough to justify the extra per-license cost of TFS, which can be significant.
The old TFS Build was XAML based and very cumbersome and and not nice to work with. That said, the new TFS 2015 build system is leaps and bounds better, and is script based with lots of web hooks and 3rd party integrations; very similar to Team City. Also, TFS now supports Git, so you are no longer confined to using Team Foundation Version Control (TFVC). Also, with TFS you can use your own on-prem installation, or can take advantage of a hosted solution through visualstudio.com. TFS is great because it's one completely integrated environment (work items, planning, builds, tests, deployments), whereas Team City is just a build solution. When this question was originally asked in 2010 I would've recommended Team City hands down. Now though, the 2 are very competitive. I would say that it would maybe boil down to if you want an all-in-one solution, then go with TFS, but if you are looking for purely just a build system, then Team City.
Comparing TeamCity to Visual Studio Team Services (the latest cloud-based offering from Microsoft):
Both work great for implementing a continuous integration process
TeamCity is more mature and everything just works.
Visual Studio Team Services by contrast is constantly evolving to catch up with TeamCity and some things just don't work well (e.g. try triggering builds based on paths that have changes from Git - the documentation is weak and the feature itself just doesn't work (as of August 2016))
Visual Studio Team Services makes it easy to have only cloud-based agents running your build (the downside however is that each has to do a clean pull of your repository for each build which may add a minute or more to the build). Both can also support local build agents which do not need to wipe the working directory for each fresh build.
But in either case I would highly recommend you also look at CakeBuild which moves most of the configuration information about how to do a build out of the CI system and into C# code that is in your Git repository along with all your other source code. With CakeBuild you can run the same build locally as you will run in the CI system and if you need to go back a month to build a specific version you have the source code and the build script to do it.
With CakeBuild in place you are now free to easily switch between TeamCity and Visual Studio Team Services.
The only downside to CakeBuild is that all your build steps are bundled into a single task in the CI system which makes reporting slightly less nice and may involve some extra work to get the test results out into a format that the CI reporting system can use.
MS is years behind in the TDD/CI area
Being one who has TDD'd for 4 years now you are correct. MS is still not even promoting it nor do they offer tools that work well with the TDD flow.
Don't get stuck dealing with Visual Studio for any kind of automation, source control, or agile workflow period (stop using TFS please!!). That stuff even though they say is "new" is monolithic and always comes with weird issues and bloat. It is always painful.
I've used Team City and it's simply amazing, things work, it's designed for usability, and it's simply designed well and compatible with most all test tools, etc. Fine use Visual Studio for code, nothing else. Look for external and open source tools to help build a better CI. The "you can do everything right in VS" sell is not selling, and it's not working. People nowdays are used to and always combining different tools from the outside to get things done. Relying on all MS toolsets is just not the way to go IMO for .NET. MS likes to sell "hey you can just do everything right here". But you end up with nothing but pain when you go that route and drink their koolade (TFS, MS Fakes, etc.).
If you plan on doing TDD, you definitely don't want to be using all MS tools. You'll either be pushed down "their way" of doing things which is often proprietary and/or bloated when you try to TDD with their tools or be totally restrictive. For TDD you need to be able to have some flexibility and choices when you decide to layer in different test frameworks, assertion libraries, etc.
Add Octopus on top of Team City, and it's stellar...you will simply fall in love with it as developer or for anyone doing DevOps.
Stop trying to rely on Microsofts continued failure at agile tool offerings
Start looking outside the box and try new things is what I keep repeating to the .NET world, me being a .NET developer in the past and who has tried new things outside the MS world.

Why not use TFS as a build / CI solution?

Currently our build solution is set up using TFS + MS Build scripts.
TFS is also being used as a CI server.
I've seen several posts on this site telling people about other CI solutions.
Are there any compelling options to move to another Solution for our build system?
Or in other words what are we missing out on by using TFS?
EDIT
We are using TFS for source control / issue tracking and I think this is a good solution, im just wondering about the other options for build server / CI server integrating with TFS.
The main problem with TFS is that if you have a server crash, restoring your source code is non-trivial. This is unbelievably bad since the most important aspect of any source control system must be to be fail-resistent, at least if you perform all backups as you should.
IMHO the greatest benefit of TFS is that everything is integrated in the IDE: work items, bug tracking, CI, Code analysis, ...
I have used TFS in the past but my current company use SubVersion/Team City/FogBugz to implement the same functionality provided in the TFS solution.
I would say that from a technical implementation perspective, you can gain additional features from a non-TFS system that TFS would be a nightmare to configure.
However, that said, one of the biggest reasons for not going for TFS is the cost of running such a system. The big advantage of TFS is the integration of everything which makes people use it more as the more you put in, the more you get out. The worst case scenario is a system that people can’t be bothered using which adds no value to the company’s development.
In my opinion, if you are already on TFS and can afford to stick with do, do just that!
