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.plis 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.

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.
