Right Click the VM, and Click Migrate, follow the wizard and select the new datastore.

Make sure you have no snapshots on the VMs, before Migration.

The RDM is attached to the VM.

Is the RDM physical or virtual?
There is a caveat for physical RDM.
Only pointer will transfer over, NO data.

Yes, as long as they are virtual RDM's this can be done "hot".
You will need to do an advanced vMotion to move VM and RDM.
