The insidious urge to fix what ain’t broke has arisen. I’ll probably follow the official documentation, unless someone has a better suggestion.
I’m not running anything unusual and I haven’t done much, if any, “customization”. I update packages maybe a couple of times a week, so they’re current.
Should I go ahead and put myself through this now, or wait until support is dropped and I’m forced?
Backup your data: the stuff you can’t just reconstruct.
The go for it. Worst comes to worst: reconstruct the system and applications and reimport the data.
If you have capacity: do it in a VM first.
