You can use Dynamic Provisioning for Mainframe in combination with Volume Migration to migrate DP-VOLs.

The following figure shows the interaction when the Volume Migration source volume and target volume are also DP-VOLs.



The following table lists the supported Volume Migration and Dynamic Provisioning for Mainframe volume combinations.

You cannot specify a Dynamic Provisioning for Mainframe pool-VOL as a Volume Migration source volume and target volume.

If you specify a DP-VOL as the source volume, you must not specify the DP-VOL that uses the same pool of the source volume.

For more information about the migration of DP-VOLs used in the following software products, see Volume Migration User Guide for VSP One Block.
