[opensuse] Can't upgrade 11.4 to 13.1

I'm trying to upgrade my firewall from 11.4, the old Evergreen to 13.1, the next Evergreen. However, when I try I get this error message, which I have never seen before. "The installed product is not compatible with the product on the installation media. If you try to update using the current installation media, the system man not start or some applications may not run properly." Is 13.1 too far from 11.4? Will I have to upgrade to 12.x first? As I have a lot configured on this firwall, I'd prefer to upgrade, rather than fresh install. tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
