We are in the process of upgrading our GW 6.5 (NW5.1SP8) to GW 7 (NW5.1SP8).
We want to upgrade our platform from NW5.1SP8 to WW6.5SP3
We have to move our GW system from one tree to a new tree

Our plan is to proceed the following way

1. Upgrade Groupwise on the NW5.1SP8 servers
2. Move Groupwise system to new servers on NW6.5SP3
3. Move servers to new tree

Does anyone have an idea regarding this issue?
