Will be upgrading from a NW51SP8 server to a new server running (from the
install CD) NW65SP7 pre-migration server.

The source server has 8.7.3.7, destination 8.8SP2.

The source server is the master of the root for the tree. Other servers
(NW51SP8 as well and eDir 8.7.3.7) have read/write replicas.

- Firstly, while I would normally do a full backup first this takes
overnight and I'd like to use the overnight to run the migration copy, so
that I can get the new server up and running faster and cut down on down
time. Is it relatively safe to skip the backup? If memory serves there's a
routine to reverse the migration if it should go faulty. However doesn't
the file system stay intact right until the end of the migration being a
success? Am I taking any real chance by not doing a full backup of the file
system?

- How about eDirectory? I could run a backup of eDir using Arcserve, and
further protect with DSREPAIR -RC. What if I made one of the other NW51SP8
servers master of the root before doing the migration, is this necessary as
a further precaution or even possible? I'm thinking I can't do this since
eDir 8.8SP2 will be on the destination server, and believe you have to have
the master of the root upgraded first.

- Presume there's no issue running the migration wizard with the source
server having eDir 8.7.3.7 and the destination pre-migration server having
eDir 8.8SP2?

Thanks in advance
James
