The replication server licenses provided with ASE Edge Edition can ONLY be used in a Warm-Standby DR environment for full database replication, not specific tables and columns. In addition, the replicated databases can NOT be used for any other purpose (e.g. reporting) except when failed to in a DR situation (so would support your future use case).
Based on your description of the current use case for the replicated data, you probably still need to keep the old Replication Server licenses intact as these are full-use licenses. Also, the destination ASE instances must also be full-use as they are not being used for DR currently, but are active DBs.
