Rules to Better TFS 2010 Migration

There are many options for migrating to TFS 2010 from TFS 2008.

Always plan for a catastrophic disaster, in the event of errors when testing:

1. Prepare a new image. We recommend running Windows 2008 R2 Server x64using Hyper-V Manager. Your options are:
   1. Manually build a server
   2. A syspreped image (this will be quicker)
   3. System Center Virtual Machine Manager (recommended, quickest)
2. Add the roles
   1. Application Server
   2. IIS
3. Install SQL Server 2008 x64 default configuration
4. Install SQL Server 2008 SP1
5. Run www.ssw.com.au/ssw/Diagnostics/ and get all green ticks

Once you are ready to start you need to make sure that no one can access the existing TFS 2008 server while you do the migration.

1. Run the excellent DogFoodStats by Grant Holliday. These are queries on the TFS2008 database to give you stats about number of files, number of users etc. http://blogs.msdn.com/bharry/archive/2007/12/02/tfs-statistics-update.aspx 1. Record the Number of files 2. Record the number of Iterations

TFS2008:

===========================================

Files

1        28052

2        335168

-- Compressed file size:

11837952896

-- Uncompressed file sizes:

24868196032

-- Areas & Iterations:

1096

Example: Dog Food Stats on TFS2008 Make sure that you save the numbers so you can compare it to TFS 2010 later...

Run your daily backups to provide a safety net should things go wrong.

Since we recommend doing a "move based upgrade", we don’t like the "in place upgrade" option, these are the steps:

1. Copy the TFS2008 backups to TFS2010 server (e.g. C:\TfsBackups)
2. Restore all the databases to TFS2010’s instance of SQL 2008
3. Install Team Foundation Server 2010
4. After the install has completed the Team Foundation Server Configuration Wizard will open
5. Select Upgrade | Start Wizard 
6. Click "Next" 
7. Click "List Available Databases"
8. Select the TfsIntegration database
9. Check "By checking this box, I confirm that I have a current backup"
10. Click "Next" 
11. Select "NT AUTHORITY\NETWORK SERVICE" for the System account
12. Click "Next" 
13. Click "Next" 
14. Click "Next" 
15. Click "Next" 
16. Click "Next" 
17. Specify the TFSService account
18. Click "Next" 
19. Click "Next" 
20. Click "Next" 
21. Click "Next" 
22. Click "Next" 
23. Click "Configure" 
24. Have coffee (2 hours) BTW: A good user interface should have a coffee image [TODO: Martin to create new rule in "Rules to better UI"] [TODO: Martin to add suggestion to TFS] 
25. Click "Next" 
26. Click "Close" 
27. Click "Close" 
28. Change the DNS entry for tfs.northwind.com to point to TFS2010 on
    1. Internal DNS
    2. External DNS

Since you have to deal with your system admins, this job will take the longest. Speed it up by buying a Red Bull for your system admin

All of the hard work has been done, now you need to do a quick test.

Running the "Dog Food" stats on your new TFS 2010 server is a good way to see if the upgrade was successful. You should check the new values against the stats you noted down from your TFS 2008 server.

Getting someone else to test the migration is the best way to make sure that you have not missed anything.
