Re: LPAR OS versions dependencies

So, what I'm gathering from the responses is this :
1. Upgrade to V5R3 (Which I was planning to do regardless of this 
conversation)
2. If I needed to use the 550 for DR, I could.
3. Since there is no longer a 'primary partition' on the 550, I could 
be at V5R3 and another LPAR (or all of them) could be at V5R4, 
V5R5, ...V6Rx or whatever.

I appreciate the input on the older hardware and thinks to think about 
and I certainly will review that, but this was more of a question on 
purely the 'version restriction'.

Thanks
