Migrating the Consumers

For each consumer in the replicated topology:

1. Reroute clients to another consumer in the topology.

2. Disable any replication agreements to the consumer you want to migrate.

3. Stop the consumer.

4. Migrate the consumer according to the instructions under Chapter 1, Overview of the Migration Process for Directory Server.

5. Start the consumer.

6. Enable the replication agreements from the hubs to that consumer.

7. If you have migrated the data, check that replication is in sync.

8. If you have not migrated the data, reinitialize the consumer.

9. Reroute clients back to the consumer.

The following sequence of diagrams illustrate the migration of a consumer, as described above. The first diagram shows the version 5 topology before the migration.

Figure 4–1 Existing version 5 Topology

The first step involves rerouting clients and disabling replication agreements, effectively isolating the consumer from the topology.

The next step involves migrating the version 5 consumer.

Figure 4–3 Migrating the version 5 Consumer

The next step involves enabling the replication agreements to the new consumer, initializing the consumer if necessary, and rerouting client applications to the new consumer.
