I have two different servers(A1, B1) with mysql-5.1.73 and currently, I'm replicating DBs with another two servers(A2, B2).
I would like to know is it possible to do a centralized DB replication, which means replicating DBs of both Master_A1 and Master_B1 to a single Slave_A2.
P.S: database and their table names will be same in both Master servers.
