You should update your firmware.
If you still have access to DWC. Upload these 4 zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
Backup your existing config files in the sys folder in case you want to switch back to RRF2. It’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.
These documents will come in handy during the conversion.
