I have 5 laptops with databases i need to replicated on a central server. The problem is that I didnt convert to replicas. The structure of the databases are exactly alike. I got one laptop to work. I made a replica of its database then put it on the server and replication works fine with that laptop. I'm sure i have to convert the rest to a replica but is there a way i can replicate databases not in the replica set? I cannot lose all the data in the rest of the 4 laptops. Any suggestions?
