We tried the other way around a couple of times, i.e. moved a Sup720
from a 7600 chassis to a 6500 chassis. The only kind of "problem" we ran
into was to sometimes not remember to have a copy of the software that
will actually boot in the other chassis. With SXF this has never been a
problem, only with SRB/SXH and newer.

Otherwise it has been painless.
