During the three stages of data migration, accessing the information changes from using physical to
virtual information.
• Before data migration (using physical information)
Before data migration, a host uses physical information to access the migration-source resources.
• During data migration
The path from the host to the storage system is changed from the migration source to the migration
destination. Configure virtual information on the migration-destination resource, and then migrate
the data from the migration-source resource. Changes to the resource group to which the volume
belongs cannot be assigned until data migration is complete.
• After data migration (using virtual information)
After all of the source resources are migrated to the destination, you can assign resources or allocate
volumes to virtual storage machines. Then the host can now use virtual information to access the
resources on the migration-destination storage system.
For resources that have virtual information configured after data migration:
• To manage copy pairs by using the resources of a virtual storage machine, review the prerequisites
for system configuration. For details, see the HP XP7 Command View Advanced Edition Adminis-
trator Guide.
