It is required for an upgrade from an early RISC release like V3R7, but *not*
for a CISC to RISC upgrade like V3R2 to VxRy.  I just did a V3R2 to V4R5
side-by-side roadmap upgrade for a client last month.

I also did a V3R7 to V4R3 to V4R5 last month, because V3R7 can't go to anything
higher than V4R3 in a single step.

You will undoubtably be starting with a new box, with the feature code 0203 to
specify you are doing a "side-by-side" upgrade.  This is one of the CISC to RISC
roadmap options.  It is much more detailed than simply restoring user libraries
from the old system, but when followed to the letter is a straight-forward and
reliable process.

It is a big deal for those on V3R6 and V3R7 -- early RISC release which did not
require a software subscription.
