Moved Computers. Been away a year. Restore AddOns from backup or No?

[EverApri]

Hi. I'm moving from a MAC to a PC. I can't believe I'm forgotten so much of how this all works.

Is Minion still the recommended way to install AddOns?
Does my ESOUI account show which addons I had installed previously?

I have a folder with backups of my AddOns from 2019. It is on an external hard drive.

Do you guys think I should just start over and reinstall all AddOns ... or have any of you restored your AddOns from a backup?

Thanks for any help and or advice.

Regards.
