Hi,
The firmware you specified is used with GMTSoft, which is previous plc editor. You cannot upload the project made using this editor from PLC. If you wish, you can update the Firmware and Bootloader versions of the PLC with our new and long-used PLC editor, GMTSuite, and rewrite the program to use it. You should know that with the update process, the ladder project running in the PLC will be deleted. Have a nice working day.
