I am trying to migrate projects from TFS 2010 to TFS 2012. I am following the steps given below:
- Detach Team Project Collection
- Back up the collection database and restore it in target machine.
Some of the projects are in DefaultCollection project. When I try to attach the collection in Team Foundation server, I do not get the option to restore DefaultCollection. I am not able to connect to this collection from visual studio. I am not sure what I am doing wrong here. Have I missed any step during the migration? Any help would be greatly appreciated.
