In the case where SW doesn't already have a canned process to use for upgrades, first I check the online shared templates within Thwack to see what others may have figured out and shared.  You should be able to see that within one of the pages/tabs inside NCM.  If you dont' find what you want, try various searches to guess what others might have called their shared upgrade template.

If nothing useful has been shared by others, that's when I document literally every step of the upgrade, and then take any of the other templates and customize it to use the steps I've documented.

And then test, test, and test again.

If you go this route, be aware that small changes in future IOS or hardware versions may require you to modify your new template--or even scrap it and start from scratch.
