When the timer expires, the first subscriber node, plus all other subscriber nodes that requested replication within that time period, begin a batch data replication with the publisher node. The default database replication timeout value is 300 (5 minutes). Restore the timeout to the default value after the entire cluster upgrades and the subscriber nodes have successfully set up replication.
