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.
