We're planning to migrate a project collection currently hosted on TFS 2010 to TFS 2012. We want to keep the current installation running while resolving any issues that might arise, so we need to copy the current project collection to the new server.
However, TFS doesn't allow us to attach a restored database backup directly. The database first must be detached from the original TFS installation. We can get around that limitation by cloning the project collection and detaching the clone, but we're not sure whether that would also impact the original project collection.
Does TFS lock the original project collection while it's being cloned?
