You can migrate the following types of SI pair volumes as Volume Migration source volumes:
- L1 P-VOL with up to two S-VOLs.
- L2 P-VOL with at least one S-VOL.
To assign another type of SI pair volume as a Volume Migration source volume, you must delete the SI pair first.
SI pair volumes cannot be migrated as Volume Migration target volumes.
Volume Migration volumes cannot be used in SI pair tasks; you must release a volume in Volume Migration before you can use it as an SI volume.
