I'm looking to upgrade my 6000 controllers from 220.127.116.11 to 18.104.22.168.
Looking at the the 3.4.2 upgrade guide under the heading "upgrading from 3.3.x and Earlier Release" the third step says "reset controller to factory-default mode"...
Is this really a requirement? Has anyone else upgraded code without factory reset? This will be my first upgrade on an Aruba controller, is factory restting before pushing new code common?

The Upgrade Chapter covers every upgrade scenario (including RN releases) from version 2.5 including Best Practices. Even though the chapter discusses upgrading to “5.0”, the upgrade procedures stand on their own regardless of which version you’re upgrading to.
Short answer is one “reboots” the controller but certainly does not reset to factory defaults. Attached is the Chapter from the 5.0 Release Notes.

By the way, I personally do not recommending upgrading selective controllers in a master/local scenario, because you lose the ability to change the config on the locals that are not upgraded. There has to be a very good reason NOT to upgrade all of your controllers in that scenario.

This assumes that there are no config changes as part of the upgrade itself. This isn't always a safe bet, which is why the best practice is to upgrade all at once or sever the communications between master/locals until they are all upgraded.
