Well, if your requirement is to free up the disk from one diskgroup than instead of creating new diskgroup you might consider just adding disks to DtDg1 and removing disk that you need to use for something else. ASM will automatically do rebalancing for you and free the disk that you are dropping from the disk group.

There are few gotchas:
- you can't change diskgroup mirroring type - you should mix disks with different performance in one DG (well ok only during migration to new disk group). ASM doesn't automatically rebalances the load based on performance/response of disks.
