migrate data from TFS 2008 to an already working TFS 2012

Question

I read everything about the upgrade process from TFS 2008 to 2012.

but my situation is a bit diffrent. I need to move data from tfs 2008 (sqlserver 2003) to tfs 2012

Answer 1

After trying everything (without touching the real Data) I succeeded.

I decided to split the upgrade process to two 2008-2010 and 2010-2012.

1. I copied the 2008 TFS db's to the neNew SQLSERVER which is being used by the TFS 2012
2. I added another VM with TFS 2010
3. I run from TFS 2010 the upgrade wizard which identify the 2008 copied db's
4. The result was a new collection attached to TFS 2010
5. I detached the collection On the TFS 2012
6. I run attach collection (the TFS 2010 one) and this upgraded the collection.

The process worked smothly.

Thanks all for the Help
