Reinstall OS Ubuntu 18 to 20.04 and had to set it all up again (Solved)

Yes I back it up all. I made a link to the backup to Link shortcut /usr/lib/plexmediaserver to /media/WD-MyDrive-2TB/plexmediaserver were the backup is.

Renamed the new /usr/lib/plexmediaserver folder to /usr/lib/plexmediaserver~ so I did not delete it.

But when I got to the URL I get a 404 Not Found error.

Then rename the link back how it was refresh the link it it comes up takes a little bit and all my folders show up at the left side but with ! on each of them.

Have some links I pointed to the back up in the /usr/lib/plexmediaserver folder.

The /lib is a link to my backup.

That seems to get the names of the folders but not that database I guess.
