Using Backup from 1.3 after setting up version 2.x

[dannyv1101]

Hi, I tried to update from version 1.3 to the newest version.

It end with the error cause of the configuration.yaml.
So I tried to install the pnpm. It also failed. So I think there is something else wrong with my system.
So I made a backup with the webserver and do a complete new installation on a other sd card.
Can I use the old backup for the new installation? And how do I install the backup?
I really do not want to setup 83 devices new. Cause I also have to install them in iobroker also if I have to make everything new!

But if it dont work I have the old sd card I can use.
