After you have installed using a customized installation package (CIP), the system is maintained as if installation had been performed directly. You can use CIPs to apply maintenance patches or interim fixes to any installation of WebSphere® ESB.
There is no substantive difference between an installation of WebSphere ESB created with a CIP and an installation created by another route. Therefore applying maintenance, refresh packs, fix packs and interim fixes is identical to the usual methods. See the related tasks for details. However, do note that there are specific steps to rolling back maintenance that was applied with a CIP.
Subsequent topics describe how to apply or roll back maintenance to a WebSphere ESB installation created with a CIP.
