TFS2005 to TFS2008 Migration Question

Feb 21, 2008 at 2:42 PM
Is it possible to use this tool to migrate source code (with history) from a Team Project located on a TFS2005 server to a Team Project located on a TFS2008 server?

Or am I required to upgrade my TFS2005 server first?

From my experience I always do a back up and restore from my production TFS 2005 server to a VM, then upgrade the VM from 2005 to 2008, and then migrate from 2008 to 2008.

Thanks for the response. Let me make my question clearer:

I know this tool supports migrating code from a TFS2005 server to another TFS2005 server. Does this tool SUPPORT migrating code from a TFS2005 server directly to a TFS2008 server? Or is this known to be impossible?

I believe the tool supports migrating code from a TFS 2005 server to a TFS 2008 server directly HOWEVER in my own experience with migrations I have NOT been able to directly migrate and have the migrated source code or work items correctly work on the destination server. Therefore, my recommendation is to backup from a TFS 2005 to another TFS 2005 server and then upgrade that machine/VM to TFS 2008 server and then migrate from that TFS 2008 server to your destination TFS 2008 server.

I've done about 30 migrations and I've found this process to yield the best results.
