Netscape DIRECTORY SERVER 6.1 Installation Manual page 90

Migration Procedure
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.
NOTE
To migrate this topology using Approach 2, follow these steps:
Migrate Directory Server 6.x on ServerA following the instruction given in
1.
section "Migrating a Standalone Server," on page 80.
Migrate ServerB to Directory Server 6.x following the instructions given in
2.
section "Migrating a Standalone Server," on page 80.
Recreate migration agreement between ServerA and ServerB.
3.
Re-initialize ServerB.
4.
Upgrade ServerC to Directory Server 6.x, and make it a read-only replica of
5.
ServerD.
Recreate migration agreement between ServerA and ServerC.
6.
Re-initialize ServerC.
7.
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.

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.
