To migrate the XP Continuous Access Journal volumes, you must specify the target volumes
that belong to the same CLPR.
CAUTION: When you specify an XP Thin Provisioning virtual volume or an internal volume
that is used for the XP Continuous Access pair as a source volume, see Table 5 (page 19) for
specifying a target volume. The XP Continuous Access pair combination of an internal volume
as a P-VOL and an XP Thin Provisioning virtual volume as an S-VOL is not recommended.
Prevent this XP Continuous Access pair combination from being made after the volume is
migrated.
