Upgrading from TFS 2010 Beta 2 to TFS 2010 RC done

Visual Studio Team Foundation Server 2010 RC was released yesterday on MSDN. I am happy to report that today we successfully completed upgrading our production TFS 2010 Beta 2 server, to the new TFS 2010 RC. wow.

Updated: 11th February 2010– Added link to Brian Harry’s post
Updated: 12th February 2010 – Adam Cogan was not clear that there were two problems with snapshoting running servers.

The upgrade was smooth, let me tell you the steps:

note: If you are upgrading from TFS 2008 you can follow our Rules to better TFS 2010 Migration

1. Snapshot the hyper-v server 
   There are two reasons why you should never do this while the server is running:
   1. It’s Slow - Make sure you turn off your server before you take a snapshot. It took 15 minutes to get to 2% while the server was running, but turning it off had the whole operation completed in under 30 seconds. I think of this as very like the feature of Linux that let you recompile the kernel on the fly to avoid rebooting when adding drivers: Nice to have, but only if you have 10 hours to spare.
   2. It’s Dangerous - Brian Harry has an even better reason why you should never snapshot a running server .
2. Uninstall Visual Studio Team Explorer 2010 Beta 2 
   You will need to uninstall all of the Visual Studio 2010 Beta 2 client bits that you have on the server. That’s a no brainer, but you can remove them early to streamline your installation process
3. Uninstall TFS 2010 Beta 2
4. Install TFS 2010 RC
5. Configure TFS 2010 RC
   Pick the Upgrade option and point it at your existing “tfs_Configuration” database to load all of the existing settings
6. Test the server

All of our 52 developers are now up and running on TFS 2010 RC. Well…almost all. A couple of guys reported this problem even though they had previously connected to TFS 2010 Beta 2:

1. If you get this error on the VS 2008 client after the upgrade, you should check whether you have KB74558 installed, if not you can download it manually or run diagnostics to ensure your entire system is up to date.
   Figure: Error TF31001 or TF253022, but why is that link not clickable. Figure:  Check that you have the update so you can connect to TFS 2010 via “Help | About Microsoft Visual Studio”

I will be ironing out any other kinks tomorrow…

Next steps includes upgrading our build servers and moving all 52 developers over to Visual Studio 2010.

We were the first company on Beta 2 in production and I believe we are first on RC in production.
