In my environment I have 8 LPARs, the primary is V5R1, 3 LPARs at V5R2,
and the rest at V5R3. Talk about a split personality....

Primary need not be most current. Secondaries are often created
_specifically_ in order to host a new release in a test environment
before upgrading the primary. This is one of the selling points of LPARs
from the beginning.

As mentioned above, one requirement is the N-2 limit. One additional
requirement is that the hardware must support the release. E.g., a new
system that requires V5R4 has no current alternatives.
