Unlinking active and replica instances

In the event of a disaster scenario or after a migration, you can unlink the active and the replica instances. The replica instance becomes a separate, standalone instance. Once the instances have been unlinked, you cannot link them again, and you must choose one to use as your primary server going forward.

Use the following procedure to unlink an active and a replica instance.

To unlink an active and a replica instance

  1. Sign in to the Flex Appliance Console on either appliance.
  2. Navigate to the Remote replication page. Locate the instance that you want to unlink. Under Replication status, click Unlink from replica or Unlink from active instance.

    Alternatively, you can navigate to the Application instances section of the System topology page. Click Actions > Unlink from replica or Unlink from active instance.

    Note:

    If you unlink from the active instance, the instance must be stopped.

    You are redirected to the Activity Monitor to view the progress.

  3. When possible, the replication settings are removed from both appliances as part of the unlink operation. However, in some cases, the settings may remain on the paired appliance. If the settings remain, perform the unlink operation again from that appliance.
  4. If you use DNS and want to use the instance that was previously the replica, update your media servers and clients as needed with its settings.
  5. Start the instance that you want to use. Do not start both of the unlinked instances.
