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 4.20.7 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 4.20.7 of the Samba suite.

AUTHOR
       The original Samba software and related utilities were created by
       Andrew Tridgell.	Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       The samba_downgrade_db tool was developed by the	Samba team at Catalyst
       IT Ltd.
