NAME
samba_downgrade_db - Samba tool for downgrading AD databases
SYNOPSIS
samba_downgrade_db [-H] [-s]
DESCRIPTION
This tool is part of the samba(8) suite.
The format of the Samba Active Directory (AD) database changed in
version 4.8 and 4.11. When downgrading a Samba AD Domain Controller
(DC) to a release that is older than either of these versions (e.g.
4.11 to 4.10), the AD database must be manually downgraded before the
Samba packages can be safely downgraded.
This tool downgrades a Samba sam.ldb database from the format used in
version 4.13.17 to that of version 4.7. The v4.7 database format can
safely be read by any version of Samba. If necessary, later versions of
Samba will repack and reconfigure a v4.7-format database when the samba
executable is first started.
Note that all Samba services must be stopped on the DC before running
this tool. Once the tool has run, do not restart samba or modify the
database before the Samba software package has been downgraded.
OPTIONS
-H [sam.ldb file]
Link directly to a sam.ldb file instead of using path in system
smb.conf
-s [smb.conf file]
Link directly to smb.conf file instead of system default (usually
in /usr/local/samba/etc/smb.conf)
VERSION
This man page is complete for version 4.13.17 of the Samba suite.
