Cloning - ESP32-S3 Development Board

I have an RSP32-S3 development board, and it has firmware on it from a company that used to supply us and is no longer in business, so we need to clone the software from one of ours and put it onto another.
Can someone explain how we do this, please and what equipment we would need to do it?

We are not software guys, so this is new to us. The screen is used on a machine we use in our daily work.

Thank you in advance.

If the ESP hasn't been 'locked up' against firmware read out, you should be able to just connect via USB cable to the "USB" port and read&write the flash contents using e.g. esptool.py.
