Upgrading from 3.14.4 to 4

Using the information here: https://github.com/frappe/frappe-bench/blob/master/Readme.md

I have added MariaDB repos and installed all dependencies.

This is as far as I got:

Hi,
You have to pass the path to old erpnext directory to the command.
Please remove the site directory and try running the command again.

Will add a validation for this.

Thanks,
