RS-232 module to Ethernet to Serial module, a lot involved?

Hello, I currently use the RS-232 module and thinking of switching to the Ethernet to Serial module, is there a lot of programing involved for this to work or will it be just a simple swap the module?

It depends on how your software is written. The Ethernet module will rely on a TCP library as opposed to a serial library so any calls directly to the communications channel will need to switch over. i.e.
serial.write(command)
would need to change to something like
socket.write(command)

The commands to the controllers will remain the same though.

Thanks Jacob! I appreciate the quick response.
