Hello, Here's my test result of PreUpgrading from F13 to F15, I've also updated F15RC3 test result wiki page. System: https://fedoraproject.org/wiki/User:Athmane/Fedora_Testing Test case: https://fedoraproject.org/wiki/QA:Testcase_Preupgrade_from_older_release Result: PASSED Details: - System boot and halt correctly. - Network configuration is the same. - yum and rpm are working. - Postfix and OpenSSH server are running. Notes: Since F13 use PAE kernel by default, when I preugraded I get the same F15 version of PAE kernel. I you need the standard kernel, install it after the preupgrade, then edit grub.conf to make it default, reboot and now you can remove 'kernel-PAE' (you can't remove the current running kernel with yum). # yum -y install kernel # edit grub.conf # reboot # yum -y remove kernel-PAE -- Athmane Madjoudj RHCE -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
