I think it's less work, when the demote doesn't work clean, as it sounds
in the past from some users on the list. If you have to manually remove
entries in the databases, I think the "keep IP and name" way is easier
if you can go this way.
- Setup the new server with the same IP and name.
- Copy your samba installation to the new host (use 'tar --xattrs',
'rsync --xattrs' or what ever prevents the extended attributes). Put it
exactly to the same location than it was before (e. g. /usr/local/samba/)
- Re-compile Samba (same version!) on the new host with the same
'configure' options and 'make install' over (just to make sure, that the
binaries are linked to whatever your new system is shipped with).
- Start Samba
- Testing (directory replication, logon, etc.)

I'll try putting this into a HowTo for the Wiki. But I can't promise if
this weekend. I'm currently working on two other HowTos. So less time
and so much work... :-)
