move domain and po to new partition

Due to the need for more storage I need to move my gw directory structure to a new partition. I stopped my gw system, copied the directory structure over. went in to C1 and changed the unc path for the domain and the po, then attempted to start the gw system and nothing loaded. I doubled checked the path and I know that the partition was mounted since I could both copy to it and browse to it when double checking the path in C1. What else did I need to do? This seemed easy to do, but...

I would appreciate any help. Thank you.
