The absolutely easiest way is to use TDMF, FDRPAS, etc., to move your existing volumes to the new larger volumes on the new storage unit. You then run ICKDSF to pick up the new size. If your VTOC size is pretty small you may run out of VTOC entries if you have lots of small datasets on the volume.
And if you have lots of free space on some volumes after the move, you can disable new the volumes you want to return until they are empty. TDMF did include software to replicate datasets to a different volume then rename when it is closed. You might consider doing a few EAV volumes for experimenting with then using for your largest storage group. Maybe MOD 108 (128K Cylinders). (And if you do, the Hercules group would like to see backups of a few VTOC records used by EAV high datasets.)
