@mcnahum MMOS is good for what it does, but a lot of the instructions you will find here and other places won’t work as MM is running inside a docker container… so all the maintenance work will be different

for migrate…

I wrote a little backup/restore

which saves config.js, and custom.css and the links to the modules you have installed

and then restore reads that info and reinstalls modules to a new MM install (previously completed, maybe with the automated install script, see https://github.com/sdetweil/MagicMirror_scripts) …

my idea is that you would use git to hold the info from the backup (really small as just 2 files and links)
(so you are not backing up gigabytes for stuff)

and then clone it and restore from there

the commands have help --help will display that
