I installed the beta when it came out on a VM running under C7. I upgrade every day or two and Alma upgrades have so far been seamless. It's transited from beta to RC and now to stable.
I installed the RC on a USB stick to allow me to run as bare metal on a laptop (which unfortunately has to remain as Win10). It ran fine until the upgrade to stable, but then corrupted the image during the upgrade. I reinstalled and it seems to be running fine.
I've been trialing Springdale as well (as a VM).
Requirements are: OwnCloud DokuWiki Zotero DNS slave, eventual master DHCP server NFS server Thunderbird Firefox KeePass OpenOffice FreeCAD Octave Lilypond and Frescobaldi Compilers: GNU and others. I'll probably think of a few users as I work through them!
