Before you change the configuration for a replication group, keep in mind the following:
-
Configuration changes cannot be saved until the replication group is stopped. You will be allowed to continue through the Change Replication Group wizard and make changes. However, when you click Finish on the Summary panel, a message will appear that instructs to stop the replication group. To stop the replication group navigate to the Replication Groups portlet in the Assure UI portal window and stop the replication group.
-
You cannot change the replication group name or context ID with the Change Replication Group wizard.
-
A replication group cannot be changed if the production and recovery servers and are not at the same version.
-
Certain types of configuration changes can be made dynamically while the replication group is partially active. Changes that are not explicitly identified in the table below must be made manually using the instructions in Manually changing configuration of a replication group .
