NAME
migrate-ds.pl - Directory Server Migration script
SYNOPSIS
migrate-ds.pl [--options] -- [args]
DESCRIPTION
Directory Server Migration script - migrates Directory Server from
older releases to the current release.
This script will copy instances (data and configuration) from the old
server root directory to their new FHS locations. This script does a
copy only - the data in the old instances will be left untouched. The
old instances must be shutdown first to ensure that the databases are
copied safely. During migration your migrated instances will be
started.
OPTIONS
A summary of options is included below:
--help This message
--version
Print the version and exit
--debug
Turn on debugging
--oldsroot
The old server root directory to migrate from
--actualsroot This is the old location of the old server root.
--silent
Use silent setup - no user input
--file=name
Use the file 'name' in .inf format to supply the default answers
--keepcache
Do not delete the temporary .inf file generated by this program
--logfile
Log migration messages to this file - otherwise, a temp file
will be used
--instance
By default, all directory server instances will be migrated.
You can use this argument to specify one or more (e.g. -i
slapd-foo -i slapd-bar) if you do not want to migrate all of
them.
--cross
See below.
For all options, you can also use the short name e.g. -h, -d, etc. For
the -d argument, specifying it more than once will increase the debug
level e.g. -ddddd
args: You can supply default .inf data in this format:
section.param=value
e.g.
General.FullMachineName=foo.example.com
or
"slapd.Suffix=dc=example, dc=com"
Values passed in this manner will override values in an .inf file given
with the -f argument.
actualsroot: This is used when you must migrate from one machine to
another. The usual case is that you have mounted the old server root
on a different root directory, either via a network mount, or by copy‐
ing a tarball made using a relative directory on the source machine to
the destination machine and untarring it.
For example: machineA is a 32bit machine, and you want to migrate your
servers to a new 64bit machine. Lets assume your old server root on
machineA was /opt/myds, and your new machine also wants to use a server
root of /opt/myds. There are a couple of different ways to proceed.
Either make a tarball of opt/myds from machineA using a relative path
(i.e. NOT /opt/myds) or use NFS to mount machineA:/opt/myds on a dif‐
ferent mount point (e.g. machineB:/migration/opt/myds).
If you do this, you should give the old "real" server root (/opt/myds)
as the --actualsroot argument, and use /migration/opt/myds for the
--oldsroot argument. That is, the oldsroot is the physical location of
the files on disk. The actualsroot is the old value of the server root
on the source machine.
cross: Also known as crossplatform, or 'c', or 'x'. This is when the
source machine is a different architecture than the destination
machine. In this case, only certain data will be available for migra‐
tion. Changelog information will not be migrated, and replicas will
need to be reinitialized (if migrating masters or hubs). This type of
migration requires that all of your old databases have been dumped to
LDIF format, and the LDIF file must be in the default database direc‐
tory (usually /opt/fedora-ds/slapd-instance/db), and the LDIF file must
have the same name as the database instance directory, with a ".ldif".
For example, if you have
/opt/fedora-ds/slapd-instance/db/userRoot/
and
/opt/fedora-ds/slapd-instance/db/NetscapeRoot/
you must first use db2ldif to export these databases to LDIF e.g.
cd /opt/fedora-ds/slapd-instance
./db2ldif -n userRoot -a /opt/fedora-ds/slapd-instance/db/userRoot.ldif and
./db2ldif -n NetscapeRoot -a /opt/fedora-ds/slapd-instance/db/NetscapeRoot.ldif
Then you must somehow make your old server root directory available on
the destination machine, either by creating a tar archive on the source
and copying it to the destination, or by network mounting the source
directory on the destination machine.
