For smbd (as a PDC) you need to save

	nt*.tdb
	share_info.tdb (if you have changed and default share ACLs)
	secrets.tdb (contains domain SID)
	smb.conf (include smbpasswd and any username map file)

Winbind did not exist in 2.2.0 but for future reference,
you should also save all of winbind's idmap.tdb files.


I would recommend tarring up the entire /usr/local/samba/
directory prior to the upgrade (good practice IMO).

I should go smoothly I would expect.  If something fails, you
be able to back out the upgrade as well.
