[Veritas-bu] Master migration to new server. 2 masters to consolidate to one.

I am in a similar situation. My master server (4.5) is very slow. I have
3 media servers. I am planning on building a 5.1 master in the Dev
forest and try to migrate my Prod settings over. I think it will require
me to reinstall Veritas on my 3 media servers and all 199 clients. All
are Windows servers.

Basically VMGLOB should work with trial and error - 
VMGLOB does work but it's tuff - set global database host and volume
data
base host does work,  set gdb and vdb to the new name, setgdb_host
vdb_host
make sure to take off-line all other existing master/media servers and
remove them from the domain, put them in a work group  boot the old
systems,
Veritas sees these old systems and starts acting wierd,  Not sure if the
names match but it is set global database host and set volume database
host,
then run a database backup, catalog backup and check the status, reboot
the
master sever vmglob does eventually work with rough and tuff trials.

We successfully migrated our master from Windows to Solaris back on 3.4.
The catalog was all ASCII but it was still a very complex problem that
took us a couple of attempts before we got it right.  It's not for the
faint of heart and I can see why Veritas doesn't support it.  It's not
just the catalog that is fun to migrate - it's also the policies, the
media database, etc.

I don't think is easy either...  The easiest thing to do is tell whoever
you were sharing the name with before that you have to keep it and make
them take a new name.  Yes, I know that doesn't always work...
