I plan to move my bare metal server from Fedora 29 atomic to coreOS as I understood Fedora atomic 29 is ending soon. Even if my server is quite recent and very basic, I don't want to mess things. I have been looking for good documentation, but can't hardly find good ones except the official coreos-installer github README[0]. I take the opportunity of this move to improve my knowledge of how OSTree works as it is new and I am far from understanding well all its features.
I have a few basic questions before I go.
1- Is it ok to scp the whole `/sysroot/ostree/deploy/fedora-atomic` directory as a backup before I go? 2- Is installing coreOS like an upgrade (i.e I will keep my folders like $HOME and settings in /etc) or will coreOS erase everything? 3- Am I right to think I can use OSTree functionality and install coreOS in `/sysroot/ostree/deploy/` alongside fedora atomic? This way i could reverse and boot to fedora atomic in case of issue. If I can do this, what's the correct way to install coreOS alongside atomic?
Thank you for hints, good pointers and advice.

I've never done that before. Not sure.

The fedora coreos installer consumes an entire disk (block device) so I'd recommend copying off any data you want to keep before you perform an install.

You might be able to do that but it's definitely not common or recommended. If I were you I would do one of:
- copy off all data, install Fedora CoreOS, copy back data - test out a provision of Fedora CoreOS on a separate system

Sounds wise. Thank you
