Caution
• For online Storage Migration, the capacity of the migration destination volume must be the same as the
migration source volume.
• For offline Storage Migration, stop server access to both the migration source volume and the migration
destination volume during a migration.
For online Storage Migration, stop server access to the migration source volume and the migration
destination volume before starting a migration. In addition, do not access the migration source volume
from the server during a migration.
• Online storage migration can be manually resumed on the following volumes after the process (of
deleting a copy session) is complete.
- TPV/FTV capacity optimization is running
- RAID Migration is running
- Flexible Tier Migration is running
- An Advanced Copy session exists
• For the migration destination storage system, the FC port mode needs to be switched to "Initiator" and
the port parameter also needs to be set.
• Make sure to delete the migration path after Storage Migration is complete.
