Migrating from Previous Versions
Red Hat Directory Server 6.x and 7.x instances can be migrated to Directory Server 8.0. Migration
carries over all data and settings from the older Directory Server to the new Directory Server, including
Administration Server and Console information. This is performed by running a Directory Server-
specific script,
migrate-ds-admin.pl
.
migrate-ds-admin.pl
is flexible enough to allow an
array of migration options, including migrating instances to new platforms and to migrate instances
selectively or to migrate all installed instances simultaneously.
Unlike previous versions of Directory Server, the migration script is silent, meaning that there are no
prompts and the user is not required to enter any information or approve any step in the process.
After it run, the Directory Server information and settings have been moved, intact, from the old
Directory Server instance to the new one. For the simplest migration scenario, the migration script only
requires two pieces of information with the command: the old server root path and the password for
the directory administrator.
/usr/sbin/migrate-ds-admin.pl --oldsroot /opt/redhat-ds
General.ConfigDirectoryAdminPwd=password
The different migration scenarios and migration script options are described in this chapter.
8.1. Migration Overview
Migrating from a 6.x or 7.x version of Directory Server to Directory Server 8.0 is a simple
process. Migration moves all of the user data and configuration settings, such as replication and
synchronization agreements, from the older instance to the new one. The general process is as
follows:
1. Stop all of the old Directory Server and Administration Server instances.
2. Back up the old Directory Server databases.
3.
For a multi-master replication environment.
Edit the Directory Server Console used by the
migrated server to control directory writes.
4.
For supplier and hub servers in a replicated environment.
Stop directory writes.
5. Install the new Directory Server packages.
6. Run the migration script,
migrate-ds-admin.pl
.
The migration script is silent, meaning that there are no prompts and the user is not required
to enter any information or approve any step in the process. After it run, the Directory Server
information and settings have been moved, intact, from the old Directory Server instance to the
new one.
WARNING
If Directory Server databases have been moved from their default location (
/opt/
redhat-ds/slapd-instancename/db
),
migration will not copy these databases,
but will use the directly
. This means that if you run migration, you may not be able to go
back to the old version. Migration will
not
remove or destroy the data, but may change
