I am on Ec2 instance , and updating centos 6.6 to 7.0 isnt same as updating ubuntu..!  
only fresh installs are supported, so you see, I am now with a broken site, whose backup restore i’ll have to run via CLI…!

why there are no checks before upgrading, whether OS will support this update end to end or not..!
