When you start a planned switch from the production system to the backup system, MIMIX does the following:
-
Ends the user production and backup environments on the appropriate systems.
-
Switches the selected data groups.
-
Starts the user production environment on the local (backup) system.
-
Optionally, starts the backup environment on the remote system and starts the selected data groups.
