My current server runs netware 5.1 sp5 TREEB. I need to upgrade it to
netware 6.5 and merge it into existing tree TREEA.

I have two options at this time but need more advice.

1. Build new 6.5 server with new hardware into existing tree TREEA.
Restore data from old server using tape drive. Create all users and Install
new groupwise 6.5 sp2. (only have few users and mailbox <5)

2. Use migration wizard and migrate old server with new hardware with nw
6.5. Then merge two tree.
TREEB will be another Container under TREEA

Any input will really appreciate it.
