mixing AIX 5.2 and AIX 5.3 on power5?



Looks like I may get a p550q soon. I'm not allowed to
migrate the existing applications (yet) to 5.3. I want
to install a 5.3 LPAR and begin understanding the VIO
layers.

Can I mix 5.2 and 5.3 LPARs on the same p550q? I know
the 5.2 must be at the whole CPU level and the 5.3 could
use portions of a single CPU.

Anything else?
