 If a server is already a replica of some primary, `REPLICAOF` hostname port will stop the replication against the old server and start the synchronization against the new one, discarding the old dataset.
 
-The form `REPLICAOF` NO ONE will stop replication, turning the server into a MASTER, but will not discard the replication. So, if the old primary stops working, it is possible to turn the replica into a primary and set the application to use this new primary in read/write. Later when the other Valkey server is fixed, it can be reconfigured to work as a replica.
