Change a replica type to control access to the replica information. For example, you might want to change an existing read/write replica to a read-only replica to prevent users from writing to the replica and modifying Directory data.
NOTE: You can't use this procedure to change the type of the master replica. To specify a new master replica, change the type of an existing read/write or read-only replica to master, and the original master replica is automatically changed to read/write.
You can change a replica type from either the Tree View or the list of Partitions and Servers.
Select a partition or a server.
From the replica pane, select the replica you want to change.
Click Change replica type.
Select a new type and click OK.
Confirm your request.
