After the disaster is over you will have data on the GroupWise Disaster Recovery server that does not exist on the GroupWise server. That data will need to be migrated to the GroupWise server. There are three steps to reverting back to the production GroupWise server: Pre-migrate the data to the production GroupWise server, revert to normal mode on the GRDR server, and migrate the final data to the GroupWise server.
The GroupWise server is back up, but is missing data, so isn’t quite ready to take over its duties again. We can pre-migrate data from the GWDR server to the GroupWise server to get it ready to take over again.
Run the migration tool. This gets the messages you sent or received during the DR period back to the production post office.This can only be done from the GroupWise Disaster Recovery administration console.
1a. Recovery | POST OFFICE PROFILE | [post office] | Migrate
1b. Start at "Step #1" - highlight it and press ENTER to begin the pre-migration process.
1c. After Step 1 has completed, have the users exit the client and press ENTER on "Step #2". This takes you to the Disaster Recovery POA Settings menu. Go to "Unload" and press ENTER. This unloads the DR POA but leaves GroupWise Disaster Recovery in disaster recovery mode.
1d. Once Step 2 has completed, go back to the migration menu and initiate Step #3 (full migration). Wait until this process has completed before moving to the next task (turning off DR).
Set GWDR to normal operation.
Turn off Disaster Recovery (click on the ambulance button from the web interface).
Verify that GroupWise Disaster Recovery has properly re-enabled your backup schedules and that the DR POA has unloaded.
Change the DNS A record for the production GroupWise POA. It should now reflect the IP address of the actual post office or live POA.
Hand control of mail flow back to the restored production GroupWise server and migrate the last of the data received from between the time the pre-migration began and the GroupWise server took over.
Load the production post office POA.
Migrate the last of the data.
