● Wait for user intervention before cutover—Specify if you want to perform a
manual or automatic cutover. If you select manual, Storage Mirroring Data
Migration will pause the migration process after the source data has been
mirrored to the target, which allows you time to coordinate any other tasks.
Replication will continue during this time. If you do not wait for user
intervention and cutover is automatic, the source will cutover to the target
immediately after the mirror is complete. If your source is running
applications, it is important that you select manual cutover by enabling this
user intervention option. During the manual 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.
13. Click Next to continue.
14. 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
configure optional settings, click Configure. Once you have completed your
configuration, click Finish to start the migration.
15. Monitor the progress of the migration mirror on the Monitor page.
16. When the migration mirror has completed, the target will automatically reboot to
complete the migration process, if you disabled user intervention. 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.
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.
