I have a MAster and two locals that I need to upgrade from 18.104.22.168 to 22.214.171.124. The Release Notes say:
1. Load the software image onto all controllers (including redundant master controllers).
2. If all the controllers cannot be upgraded with the same software image and reloaded simultaneously, use
the following guidelines:
They don't exactly say what to do if all the controllers *can* be upgraded/reloaded simultaneously. Nor do they say just how simultaneous it needs to be. Do I just reload the Master, wait for it to come up, then proceed with the Locals? Type reload and hit enter on all three at the same time?

Pretty sure you should do the master first, then proceed with the locals.
To the best of my knowledge, having locals at a higher level the master will prevent them from receiving any sort of updates, but that may only be when jumping between codes (eg: 5.x to 6.x).
I had my network at 126.96.36.199 and upgraded a few controllers to 6.1.x for testing. I had to change my RADIUS server IP and the only controllers that didn't receive that change via an update were the ones running 6.1.x.
I believe "simultaneous" may not be meant to be taken literally. You should be okay to upgrade within a relatively short time period - my rep told me a few days would be more than fine....with the above caveat that changes may not work until all are running same code.
