You do know that 6 x 9 = 42, works correctly in base 13 math.

42 seems like the right answer to me. Particularly if the question is,
"What do
you get when you multiply 6 by 9?"
Such a move has no effect on licensing costs if you indeed preserve the
current sysplex configuration. If you are currently under Sysplex
Aggregate
pricing, it will remain regardless of how far apart the DC's are. Hardware
costs
are another matter.
Since the PHBs want to move development and leave production alone, the
impact I see is latency to the CFs impacting common structures - ISGLOCK,
SYSIGGCAS_ECS, Operlog, Logrec, and any IXC structures, provided none of
your development DB2/CICS/IMS are datasharing with production regions.
The dumb question of the day is, what's the point? Unless they need the
floor
space, are phasing a dc relocation, or want to eventually build a
quasi-GDPS
(which means moving / mirroring tape, DASD, CFs, etc.), this is a costly
exercise in futility. I'm just sayin'...
