A hybrid is probably a good way forward. I had a career as a photographer for a while and I learned from that: going through 1000 photos takes very little time, but going through 10,000 takes an eternity. If you can star or mark your obviously important photos as you go along, it’ll take very little to print them at the end of the year.
I just had to do this. Don’t skip the release notes. They’re really good at highlighting potential pitfalls, just scroll back through and look for the heading “Breaking Changes.”
In my case there were a few, but they were only for API calls I’m not using, so I just did the update in one go and it worked out great. (Of course, I made sure to take a backup first.)
