Re: Power 8 to Power 9 swap out

[DrFranken <midrange@xxxxxxxxxxxx>]

I always build new. Then update firmware on cards and get to current fix 
levels. It's so simple why not.

It also means, if done correctly, that all your port numbers can start 
from 0 again. I love that part.

Also all your mappings will be different or wrong anyway so that doesn't 
help.

Finally I find often that I improve my mappings from release to release 
and it's simpler to do on a fresh install. I just remap as it is so 
simple to do and again since I usually am improving from my previous 
mapping this is required.
