8.15. Replication with Earlier Releases

This section provides information on how to optimize replication with earlier releases of Directory Server. Directory Server 8.0 can be involved in replication with earlier releases of Directory Server, providing the following conditions are met:
The following restrictions apply:
The main advantage of using Directory Server 8.0 as a consumer of a legacy Directory Server is to ease the migration of a replicated environment. For more information on the steps to follow to migrate a replicated environment, refer to the Directory Server Installation Guide.
To set up legacy replication, do the following:
  1. In the Directory Server Console, click the Configuration tab.
  2. Select the Replication node, and click the Legacy Consumer Settings tab in the right pane.
  3. Check the Enable Legacy Consumer checkbox.
    This activates the fields in the Authentication box.
  4. Specify the supplier bind DN that the legacy supplier server will use to bind to the consumer.
    Optionally, specify a password at least 8 characters long.
  5. Click Save.
  6. Now configure legacy consumer settings for each replica that will receive updates from a legacy supplier.
    1. In the navigation tree, expand the Replication node, and select a replica that will receive updates from the legacy supplier.
    2. In the Replica Settings tab, select the Enable Replica and Updatable by a 4.x Replica checkboxes.
      These options are the only ones required for replication to work. Optionally, specify a replica ID. It is not necessary to specify a supplier DN because the one specified in step 4 will be used.
    3. Click Save.
  7. Repeat step 6 for each read-only replica that will receive updates from a legacy supplier.
  8. To complete the legacy replication setup, configure the legacy supplier to replicate to the Directory Server 8.0 instance. For instructions on configuring a replication agreement on a 4.x Directory Server, refer to the documentation for the legacy Directory Server.

NOTE

The Directory Server Console will not prevent you from configuring a database as a read-write replica and enabling legacy consumer settings. This makes migration easier because the Directory Server can be configured as it should be after the migration and legacy consumer settings only have to be active for the duration of the transition.
