Hello, I did a minimal install in Virtualbox for Centos 6 and tried to upgrade using the upgrade tools, from centos's repo[1]. But this tends to fail[2]. preupg --list comes up blank. After this I directly proceeded to use redhat-upgrade-tool, as it turns out I need to use --force since preupg failed. The exact commend used is "redhat-upgrade-tool --force --network 7.0 --instrepo http://mirror.centos.org/centos-7/7/os/x86_64/" This works, I encountered errors like[3], but after installing the CentOS 7 keys manually everything worked out. In the end I had a bootable and upgraded CentOS 7 box.
Cheers, Gaurav
