add second destination for goldengate microservices

cptkirksh

I have GGMA 19.1 installed and am moving data between two 18c DBs. I want to add a second replicat target on a 19c DB. Can I use the same extract and just populate the schema with the structure via expdp metadata_only and then create a new initial load extract and then start the new replicat by a scn on the other extract? Is this a wise thing to do or should I just build a new extract and go from there? Thanks.
