THIS is the safest
way to upgrade a running system: Make multiple partitions.
No, that's definitely not the safest way. Jon's right. Swap hard drives.
You can't screw up something that's not plugged in!
If you don't want to do that, then at least image the drive to another device,
like a USB drive, then unplug the drive and put it in a safe place.
Been there, done that.

Swap out the HD? No. Yo can install quite a few copies of Linux+EMC on
one drive then chose which to boot from the boot menu. THIS is the safest

Then it is easy to copy from the old system, you boot the new one and mount
the old system read-only and copy from it.

My paranoid gene tells me to ask.
Your paranoia is GOOD! I would not update the system. If
you want to check out the newer version,
at the VERY LEAST, just swap out the hard drive, and install
a completely new system from the ISO.
If the computer is pretty old, it might be time to update
the hardware as well.
You can copy over your config file set and machining
programs from backups, or using whatever removable media you
have available. Most likely, you will have to make some
small adjustments to your configs files to make them work on
the latest LinuxCNC version. The release notes usually
describe what needs to be done accurately.
This is the safest way to do things.
