Creating migration groups on VDGs
If you add multiple virtual disks to a VDG, you can use a migration group to migrate all VDG members
together. Since the migration source element is a VDG, all snapshot operations (such as redirecting
write I/Os) are synchronized for all VDG members. For information about creating a VDG, see
“Working with virtual disk groups” on page 123.
In order to support the creation of a migration group, a VDG must fulfill the following conditions:
• No other snapclone, migration, or mirror tasks can be running currently on the VDG.
• The VDG must have members.
• The VDG must not have any snapshots as members.
