Migrating a Replicated Topology

Directory Server Enterprise Edition 6.0 does not provide a way to migrate an entire replicated
topology automatically. Migrating a replicated topology involves migrating each server
individually. Usually, however, you should be able to migrate your entire topology without any
interruption in service.
This chapter describes the issues involved in migrating replicated servers, and covers the
following topics:

Overview of Migrating Replicated Servers

Directory Server 6.0 supports an unlimited number of masters in a multi-master topology. This
and other changes might mean that you redesign your topology rather than migrate to an
identical topology with new servers. See Part III, "Logical Design, " in Sun Java System Directory
Server Enterprise Edition 6.0 Deployment Planning Guide before continuing.
When migrating replicated version 5 servers, you typically start with the consumers, continue
with the hubs, and finish with the masters. This bottom-up approach involves interrupting only
one server at a time, rather than interrupting an entire branch of the replication topology. The
approach also helps you avoid potential custom schema synchronization issues between
masters and consumers.
