Hmmm. I'd look at a way to not lose e-mail. Copying over the user files is a good start, but I would consider running the new machine in parallel for a test. Can you get the old machine to send copies of all incoming e-mail to the new machine, and make sure it will accept them properly? That would test that the UIDs and all survived the tarring and still make sense on the new machine. If that works, then take what you know and learned to make the new machine compatible with the old one, then cleanly take down the old machine off line as you currently do for maintenance, rsync any new changes to spool, shadow, etc., on the old machine over the the new, then quick switch identities (IP address, host name) to the new machine and bring it up. Or something like that, -kb, the Kent who is interested in hearing correction to and comments on the above. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
