Hi Laura,
Your UNC (Universal Naming Convention) to the new server must be identical to the old server, if you want to copy the directories indicated by Steve above - where UNC was used during the original install. I've seen copying directories fail - even though the drive mapping was the same for both servers - because the UNC was different.
We typically recommend re-installing Adagio programs to a new server because if something is missed, or some underlying path or code is not the same between the servers, it's possible that unexplainable scenarios could occur, such as Workstation Install screens appearing and preventing access to Adagio.
