Big Sur Update wiped my /etc/apache2/extra I think the title is self explanatory, but to say it again, I updated to MacOS 11 and all my extra configs of Apache decided to go bye-bye.
To add insult to injury, there appeared a bunch of *.conf~previous files, who are also the default settings and not mine...
While it is just a  setback, and I can redo everything, does anyone have any idea of where and if I could find the old ones?
Edit: After finishing and recovering everything, only then did I realize that macOS kept all my changes neatly in the Relocated Items on my Desktop. For anyone looking into this in the future, be sure to check if it is there...
Just restore them from the backup you made before starting the upgrade. That's way quicker then searching for them on the upgraded system.
On APFS based systems, remember, your custom files and data are on the “data” filesystem and not on the system itself.
Also, look for a relocated items folder on your desktop in case Apple intentionally set aside your modifications.
