There is a TID available:
TID10024917 How to move GroupWise domains and post offices from one server to another
Here's what you have to do:
Assuming both servers are in the same tree, do the following:
1. Copy all GroupWise directories to the new server.
2. Launch NWADMIN (or ConsoleOne in GroupWise 6)and connect to the domain database in its new location. You will probably be prompted to do this when you launch the utility, as it won't be able to find the domain database in its old location.
3. Once you're connected to the domain database, in GroupWise View go into the domain, all secondary domains, and all post offices' details and change the UNC paths to reflect their new locations. You can do this by just browsing to the new location of the databases.
4. Next you need to install the GroupWise agents to that server (assuming you want them running there). Run an agent install from the AGENTS directory under your SoftWare Distribution Directory. Follow the prompts.
5. Next install any gateways you want running on this server.
