Running AIX 5.3 on POWER8.What’s missing from the POWER8 system on the slide below? That’s right, there’s no AIX 5.3 partition! You cannot run AIX 5.3 natively on a POWER8 system.
What would you say if I told you could run AIX 5.3 on a POWER8 system? No? Well you can, if you use a versioned WPAR! J
It is documented that versioned WPARs are supported with both POWER7 and POWER8 hardware. Refer to the following link:

I tested this in my lab. It worked as advertised. I simply ran the mkwpar command to restore an AIX 5.3 TL12 SP9 image and several minutes later I had an AIX 5.3 vWPAR up and running on my POWER8 system (S824).
