I am going to migrate a NW6.0 to a NW6.5 server.

When I install NW6.5 on my new server, I choose the premigration
pattern. This automatically created a 4 gig SYS volume.

Problem is, my source server has a single 40 gig SYS volume, and the GW
PO and DOM, the only services to be migrated, is of course on this volume.

Why do I expect this migration to fail as is?

What is the best way to get this pre-migration sys volume to fill the
existing 80 gig drive?
