Migration Procedure

4. Migrate consumers one at a time. After each migration, recreate migration
agreements and re-initialize the migrated consumers.
To better understand Approach 2, consider a fairly simple replication topology:
• One supplier server, ServerA.
• Two consumer servers, ServerB and ServerC.
• ServerA has a supplier-initiated replication agreement to ServerB and to
ServerC.
• ServerA, ServerB, and ServerC are 4.x Directory Servers.
To migrate this topology using Approach 2, follow these steps:
1. Migrate Directory Server 6.x on ServerA following the instruction given in
section “Migrating a Standalone Server” on page 92.
2. Migrate ServerB to Directory Server 6.x following the instructions given in
section “Migrating a Standalone Server” on page 92.
3. Recreate migration agreement between ServerA and ServerB.
4. Re-initialize ServerB.
5. Upgrade ServerC to Directory Server 6.x, and make it a read-only replica of
ServerD.
6. Recreate migration agreement between ServerA and ServerC.
7. Re-initialize ServerC.
When you have completed the migration of your replication topology, you can
evolve it to use multi-master replication. To do this, you must add a new
Directory Server 6.x that acts as a master to your replication topology. You
cannot change one of the read-only replicas to become a read-write replica.
For more information on multi-master replication topologies, see Chapter 8,
“Managing Replication” of the Netscape Directory Server Administrator’s Guide.
NOTE You can migrate a topology where ServerB and ServerC have
consumer-initiated replication (CIR) agreements with ServerA.
However, you cannot have CIR agreements in the new replication
environment because Directory Server 6.x does not support
consumer-initiated replication.
