I'm going to migrate our main file server NW6sp5 to NW65sp8 on new
hardware using SCMT.

My question is... can I use the migration wizard to just copy all the
files this weekend, wait a week, restart the migration wizard, copy the
files that have been updated since the first copy and then finish the
migration? or is there a better way to pre-copy files to minimize the
downtime during the migration? We're guessing around 30 hours for data copy.
