May be better (since there are 2.2.7 RPMs for 8.1 on the samba ftp
mirrors) to upgrade the 8.1 box to 2.2.7 first, and ensure that's
working fine, then migrate it to 9.0 while keeping the samba version the

Well, 2.2.7 stores the domain SID in secrets.tdb, so it would be
essential to take the secrets.tdb. Of course, you should still have a
.SID file for 2.2.2 which you should backup, and 2.2.7 is supposed to be
able to import a .SID file if it finds one ...

But, if you want to run 2.2.2 on Mandrake 9.0 you're on your own ...
