5.5. Migrating the Configuration Directory Server
The Configuration Directory Server is the Directory Server instance that maintains the
o=netscaperoot subtree that is used by the Admin Server and Console.
Before you begin, install the Admin Server and Configuration Directory Server. Make sure to configure the Admin Server the same way as you configured the previous Admin Server, the Directory Server, SSL, and so on.
The next steps differ based on whether the Directory Server 9 system will use the same host name as the previous Configuration Directory Server, or not.
5.5.1. Using the Same Host Name as the Previous Configuration Directory Server
This section describes the scenario when the Directory Server 9 system uses the same host name as the previous Configuration Directory Server.
5.5.1.1. Migrating from Red Hat Directory Server 8
In case you migrating from Directory Server 9 and using the replication migration method as described in Section 5.3.2, “The Replication Migration Method”:
- Install the new Admin Server and Configuration Directory Server.
- Set up the Configuration Directory Server as a dedicated replication consumer.
- On the previous Configuration Directory Server (on the Directory Server 8), enable replication for the
o=netscaperootback end as a master/supplier. - Create a replication agreement to the new Configuration Directory Server (on the Directory Server 9).
- Initialize that replication agreement.
This method also assumes that all the previously registered instances are going to use the same host names. If host names are going to change, then you either need to unregister the old instances, or skip the replication step and manually register the new Directory Server 9 instances.
5.5.2. Not Using the Same Host Name as the Previous Configuration Directory Server
If the Directory Server 9 system does not use the same host name as the previous Configuration Directory Server, then no migration is possible.
The new Admin Server and Configuration Directory Server will need to have all the Directory Server instances reregistered using the
register-ds-admin.pl script as described in Section 4.4, “Registering Servers Using register-ds-admin.pl”.
