Firmware update

I have a Lulzbot TAZ workhorse. It was donated to our small school and last updated in 2022. Its installed firmware version is 2.0.9.0.13. I can not get Cura LE 4.13.17 to recognize the printer due to the outdated firmware. I am afraid to up date the firmware since the Cura 4.13.17 can’t verify the printer. I don’t want to over write with wrong firmware. I don’t know what to do.
