l
User name—Highlight a DNS domain and specify a user account that has
privileges to update DNS.
l
Password—Specify the password associated with the user account you
entered.
l
DNS Servers—Click Add and specify the IP address of a DNS server in the
DNS domain. Repeat this for each DNS server in the DNS domain. If you
want to remove a server, highlight the address and click Remove.
l
IP addresses—Click Add and specify an IP address on the source and the
IP address on the target that will take over for that source IP address. Repeat
this for each IP address. If you want to remove an IP address, highlight the
address and click Remove.
Once you have your DNS updates configured, click Test DNS to determine if your
DNS updates will be successful.

11. Specify your migration shutdown options.
l
Wait for user intervention before cutover—If you select this option,
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 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.
l
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. At this point, Storage Mirroring Data Migration validates that your target server is
compatible to become your source. Errors are designated by a red circle with a
white X. (A question mark icon is an unknown error.) Warnings are designated by a
yellow triangle with a black exclamation point. A successful validation is
designated by a green circle with a white checkmark. For complete details of the
items validated during this process, see Finding a compatible target in the Full-
server protection section of the Storage Mirroring Recover User's Guide. You must
correct any errors before you can enable protection. If you have to revalidate the
