I'm thinking of retiring an old 6.5 server and replacing it with a new
one. That server only has 120GB of storage.

I have 3 options.

Netware Migration Wizard

Install new server, copy data over, install ZFD/GW/iPrint, decommission
old server. Leave server with new name, update all login scripts, slp,
other server links etc.

Do above step but also change IP back to original server so that I don't
have to deal with SLP and DA stuff for all the clients and other servers.

This server was originally a 6.0 -> 6.5.

Does the migration wizard copy sys across? I really don't want that. I
want to get rid of all the older legacy stuff there.
