How to import a configuration from Emc2 2.3?

Hello to all.
I saved the config folder of EMC2 ver. 2.3 from an old PC. Now I would like to set up a new installation of LinuxCnc. Which files are useful from the old installation? Can I transfer files directly? What are the important files?

Thanks so much.

The configs folder should do nicely if you do not have any special comps installed.

Can I safely copy the folder to the new LinuxCnc 2.7 folder?

Yes.
That is a config for a proxon, right? That is easy to set up even if you do not have the config.

There are a few minor changes to be made when using a 2.3 config with 2.7.14

You only need to pay attention to the _configuration_ changes on these pages, ignore the actual upgrade instructions.

You can just try running your existing configs and correct the errors one by one.
