2. If the system is using online migration or minimally disruptive migration, select the Host, Host Set, or Linked Hosts for which you want to migrate virtual volumes to the destination system. NOTE: All virtual volumes exported to overlapping hosts (Linked Hosts) must be exported. For example: VV1 is exported to Host1, VV2 is exported to Host2 and Host3, and VV3 is exported to Host1 and Host3. To migrate VV1, you must also migrate VV2 and VV3 because the hosts they are exported to overlap. NOTE: If a volume being exported is a member of a domain, all volumes in that domain must be exported. 3. If the system is using offline migration, select the virtual volumes to migrate to the destination system and click Add. 4. Click Next to go to the Import Volumes page (recommended), or click Finish if you want to check the configuration and run the Import Volumes wizard later. If you click Finish, the peer volumes will be created but will not contain any data until the Import Volumes step or wizard has been completed. (To run the Import Volumes wizard, see "Importing Volumes" (page 237).) Import Volumes 1. Select the virtual volumes to be configured during import to . 2. Select allocation settings. You have the option of assigning Same As Source, Thin, or Full provisioning to the virtual volumes being imported. The default is Thin. • Same As Source - Each source volume will retain its current provisioning type when imported. If you are importing virtual copies, this option assigns the parent volume's provisioning type to each copy. If your list of volumes contains a mix of Thin and fully provisioned volumes, that mix is retained upon import. • Thin - All source volumes will be migrated as thinly provisioned. • Full - All source volumes will be migrated as fully provisioned.

provisioning to the virtual volumes being imported. The default is Thin.
Same As Source – Each source volume will retain its current provisioning type when
imported. If you are importing virtual copies, this option assigns the parent volume's
provisioning type to each copy. If your list of volumes contains a mix of Thin and fully
provisioned volumes, that mix is retained upon import.
Thin – All source volumes will be migrated as thinly provisioned.
Full – All source volumes will be migrated as fully provisioned.
