Thanks Keith.
Those two branches will mostly be handling independent data.
Only time to time they will need to see a record that the other branch has been created.
I don't think there will be ant conflict. Because they will not read or edit the same row in a close time frame.
It seems a Multi Master- Asynchronous replication will be the right solution in the end.
Anyway, I will start with a single database and work my way around later.
