To be safe, you're going to have to count on it breaking everything. Do a complete Admin Reseller backup. If you've done any customizations, added any software, etc., make sure to keep what you need and to also keep notes. Keep everything on a different system.I need to upgrade my system but since yum isn't working with FC4 anymore, I need to upgrade to FC10. If I reinstall with a CD and just do an upgrade will it break anything in directadmin or should it still work?
