Issue setting up DD replication for Mtree with Retention Lock Compliance enabled

We are attempting to setup an Mtree replication between DD 6800. The source Mtree has Retention Lock Compliance enabled. We have created the replication target Mtree but when we try to initialize the replication, we get an error "MREPL ASSOC failed: Destination system is not configured for Retention Lock Compliance (5074)" Have dug through the DD:RL FAQ but not finding anything there. Unfortunately, the support on the source DD expired in June, so not able to open a support ticket. Any assistance would be appreciated.
