Switchover is a mandatory final synchronization step of every migration. The switchover involves downtime and reconfiguration of the users and applications accessing the storage system. It is recommended that a dry run is performed to estimate how long a switchover takes, before initiating a switchover. This information helps create a realistic plan for the switchover maintenance window.
