You can federate documents from a Content Platform Engine version
5.0 or later source object store that is in a different FileNet® P8
domain than the target 5.2.1 or later object store.
Tip: Do not implement IBM® Enterprise Records on both the target and
source systems. If installing IBM Enterprise Records on both systems is
unavoidable, do not federate documents that need to be managed as records within the source
system.
