Disconnecting VSS/removing VSS/VSL conf was a recommendation from TAC(For a non ISSU upgrade)....which sounded like a very unusual requirement lol.....hence my question here.

We've upgraded them successfully from 3.6 to 3.7 without disconnecting the VSS links and reloading them individually.

So re-sending), I need to upgrade IOS XE on a pair of 4500X's...Id prefer not to try/use ISSU, as they are remote switches and in production....so Im hoping someone has performed an upgrade on these boxes(In VSS) and can provide some guidance on a method that "works" :) Ive read where people disconnect the VSS link (Or shutdown those ports), and perform the upgrade on the 2 switches, then reconnect VSS....but could you do something like this: conf reg on both switches is already set to 0x2102, so the switches should honour the bootvar variables copy new IOS XE to bootflash & slavebootflash update boot var to point to new XE image boot system flash bootflash:xxx wr mem and check bootvar is updated and reload both switches: redundancy reload shelf This should reload both switches, and they should come up with the new image, and VSS should re-establish?
