To migrate a cluster, migrate each profile containing a
member of that cluster one at a time. The migration requires extra
steps not required for a non-clustered environment.
Before you begin
You must have an existing cell
containing
at least one cluster running on an older version of
WebSphere® ESB (for
example,
version 6.0.x or 6.1.x)
that you wish to migrate to a newer version (for example,
version 6.2). In
addition, you must have installed the new version of
WebSphere ESB.
Important: In a cluster, version 6.0.x or 6.1.x members
and version 6.2 members
must never run at the same time. All version 6.0.x or 6.1.x cluster
members must be stopped before you start the first version 6.2 cluster
member. Also, once you start a version 6.2 cluster
member, do not start any version 6.0.x or 6.1.x cluster
members in that cluster.
About this task
Following these steps will ensure that
you retain cluster functionality on the new version of
WebSphere ESB.
What to do next
Verify that the migration has been successful.
