PHP 7 is actually pretty good and was the version I stopped at. Upgrading to 8 shouldn't be all that bad and mostly you can just install the new version side by side with the old one. As with any interpreted language, you have to hit every page and what not in order to see if there are any issues that will arise. I don't know if at this point if PHP has a compiler as that would save a HUGE amount of time upgrading to new versions of the language.
