@Alex maybe make a backup of that SD card, and then create a new configuration from scratch using the configuration tool and the existing config as a backup.
I do believe the config.g would not require a lot of adjustments except new PID tuning since the parameters changed, but starting over may be a good idea nonetheless. It might be worth re-reading the commissioning guide to re-acquaint yourself with the basics https://docs.duet3d.com/en/How_to_guides/Commissioning
