I have two RSPs, so I'd be under the impression that I could load the new code onto the standby, reload it, then failover from the active to the standby but I can't find any specific instructions in any of the upgrade docs I'm reading, so I can't be sure.

Afaik, ISSU between XR versions isn't available yet.
