I have two NW 4.11 servers. One is a file server and the other runs
GroupWise 6.5.

I have new hardware for one server. I was planning on doing an over the
wire migration for the file server (to the new server), and an in-place with
the GroupWise server.

I believe that there is no supported migration path from 4.11 to 6.5, so
what is everyone's recommendations? I already have NW 6.5SP7 up and running
in a different tree for testing and looking at the new features.

I am assuming I MUST do them at the same time- as GroupWise would not be
very happy for long sitting around in a 4.11 and old NDS.
