This is particularly true if you use external audio hardware. Will it work? Has Apple changed something underneath that stops the drivers loading? Do I need to buy the software again to use it reliably (eg. Parallels)? I ended up ditching macos after over a decade of use and going back to Linux running Ubuntu Mate with a macos theme and switching to Windows for my audio hardware since I want to still use the same hardware longer than the 3 years Apple considers a "lifetime". It's kept my 2012 Macbook in service and maybe I'll get another 10 years out of it!
