EMC2 2.4.6 Upgrade Questions

Hello everyone, newbie here. Just a quick question. I have an old Smithy 622 mill that I acquired recently and it is currently running Ubuntu 10.04 LTS and EMC2 2.4.6 (2011). I ran my first tool path on the machine this morning using MeshCAM G-Code which worked flawlessly. My question is would it be worth while to upgrade to a newer OS and LinuxCNC version or, keep well enough alone? There is a lot of settings that I am not sure how to export or even find that could be a hassle to deal with. I am mainly interested in backlash compensation of which I think this version of EMC2 does not support? Thanks in advance!

Thanks for the info Tommy. The computer that is built into the control cabinet is an LGA 775 socket with a core 2 duo 2.6 GHZ (4 gig RAM) so not too good and not too bad I guess. The OS was loaded onto a CF card drive (4 gig) of which I had cloned through Ubuntu onto a 16 gig for safety. I squirreled away the original card so I could experiment with the copy drive. I would like to fit the new "system" on the 16 gig card if possible. I have attached the config files of my machine which at the moment are greek to me. I know a little about sketches for Arduino and it looks a bit like that to me. Anyhow, maybe someone can look at them and see if these config files would be enough for me to try and update the system. There are two ziped files of the same thing. One was done in Windows and one in Linux.

Thanks again Tommy for the concise reply. I am super excited to go out and make more chips!!!

Cheers!

Thank you for the help Andy! I will give it a try.

Cheers!
