If enabled, Replication must be disabled on every server before you upgrade Management and Security Server.
Before you upgrade: Disable Replication on every server configured for replication, beginning with the Slave servers. Then, disable Replication on the Master.
In the Administrative Console, click Configure Settings - Replication.
Select the Standalone Server Role. Click Apply.
Repeat steps 1 and 2 for all of the Slave servers and then the Master server.
When all of the servers are set to Standalone, upgrade each server.
When all of the servers are upgraded, re-enable Replication. See Technical Note 2174 for detailed steps.
