for information pertaining to the Samba-3 data files, their location and the information that must be
preserved across server migrations, updates and upgrades.
Please remember to back up your existing ${lock directory}/*tdb before upgrading to Samba-3. If necessary, Samba will
upgrade databases as they are opened. Downgrading from Samba-3 to 2.2, or reversion to an earlier version
of Samba-3 from a later release, is an unsupported path.
The old Samba-2.2.x tdb files are described in
the next table.
