As an optional part of the upgrade, you can create a replica of the Content Engine version 3.5.2 data that the upgrade steps will modify. By using replicas, you can allow the production system to continue to run during the upgrade. You cannot change production system data after you back up that system. Otherwise, you must repeat the upgrade, starting with the creation of a Content Engine quiet point.
To create a replica, you first create another Windows® server in the same Windows domain as the version 3.5.2 production system of IBM® FileNet® P8. You then create replica object stores of your Content Engine installation.
