What I've done for many years is to install any new or experimental
configurations to a different partition and add it to the boot manager.
This way you can always go back to a configuration that works as you
migrate to the other one. As you resolve issues you'll use the old
one less and less. Then I leave the old one there as an emergency
or maintenance OS, which then becomes the space I use for the next
version/upgrade (presuming the previous one ended up working out).
Drives are large and cheap these days, there's no reason to restrict
yourself to one working OS on a machine.
