coordinate any other tasks. Replication will continue during this time. If you
do not select this option, cutover will be automatic, meaning the source will
cutover to the target immediately after the mirror is complete. If your source is
running applications, it is important that you enable this option. During the
intervention time, you can stop your applications that are running on the
source. This lets you stop services cleanly on the source and let that final
application data be replicated and applied on the target. This helps ensure
your applications will start cleanly on the target after cutover.

Shut down the source server—Specify if you want to shut down the source
server before the source is cutover to the target, which avoids identity
conflicts on the network. The shutdown will occur after mirroring is completed
but before the source system state is applied to the target server.
15. Click Next to continue.
16. At the Migration summary page, you can review the choices you have made and
you can also configure optional settings. If you need to make any changes to the
selections you made, click Back to return to the previous pages. If you want to
, click Configure. Once you have completed your
configuration, click Finish to start the migration.
17. Monitor the progress of the migration mirror on the
page.
18. When the migration mirror has completed, the target may or may not reboot
automatically depending on your selection for Wait for user intervention before
cutover. If you disabled user intervention, the target will reboot automatically to
complete the migration process. If you enabled user intervention, when the
migration mirror is complete, the status will change to Ready for Cutover. Use this
time to complete any necessary tasks. When you are ready to complete the
migration, click Cutover on the Monitor page toolbar to complete the migration
process, which will reboot the target.
Once the virtual machine has been rebooted, it will become the source server.
Note: You must install Integration Services after cutover for SCSI drives and mouse
drivers to function correctly on the new virtual machine.
Your Hyper-V virtual machine will not start if the amount of memory it is
configured to start with is more than the free physical memory available. This may
happen if the amount of free physical memory changes after you have created
your migration job. In this case, you must manually modify the virtual machine's
memory settings and then manually start the virtual machine.
If your source was disconnected from the network during the cutover process, the
original job that was mirroring the data will still be active on that machine. Do not
bring that machine back on the network. If you do, the original job will attempt to
