An installation of WebSphere® ESB, version
6.2 can coexist on the same system with installations of any version
of WebSphere Enterprise
Service Bus, WebSphere Process
Server, and with certain versions of selected WebSphere products.
An installation of
WebSphere ESB, version
6.2 can run on the same system at the same time as installations of
one or more of the following supported products and versions:
- IBM® WebSphere ESB, versions
6.2, 6.1.x, and 6.0.x
- IBM WebSphere Process Server,
versions 6.1 and 6.0.x

When configuring coexistence, you must address any port conflicts
that occur to avoid communication errors. Each version of the server
must have a distinct database.
Do not confuse coexistence with
migration,
updating,
or
interoperation:
- Migration is copying the configuration from a previous
release of WebSphere ESB into
a new release. If you are installing WebSphere ESB, version
6.2 on a system that already has a prior version of WebSphere ESB or WebSphere ESB installed and
you intend to migrate to the newer version of WebSphere Process Server or WebSphere ESB, see Migrating
to WebSphere ESB for
more information.
- Updating is replacing out-of-date files or data of an existing
installation with current information. Refresh packs, interim fixes,
and fix packs are examples of updates. For more information on updating,
see Installing Maintenance Packages.
- Interoperation is exchanging data between two different
systems, such as coexisting product installations. This version of WebSphere ESB is
generally interoperable with many previous versions. To support interoperability,
you need apply the latest fix levels. See Planning for interoperability between WebSphere ESB and
other WebSphere Application
Server products for more information.
