Update Centos 6.5 / 6.6 to 7

Posted on November 17, 2014

Hi All,

I can’t find it on the internet. But is it possible to update Centos 6.5 / 6.6 to Centos 7? Or do i need reinstall the whole server again?

Thanks!! Peter

I tried to do an in-place upgrade but it fails. I did every step here: http://www.shaunfreeman.name/upgrading-centos-6-5-to-centos-7-2/

but at the end it prints out:

setting up system for upgrade grubby fatal error: unable to find a suitable template Finished. Reboot to start upgrade.

After I reboot nothing happens. I suspect it has something to do with the kernel but DO support was not able to provide any other advice than setting up a new droplet. I wish this was as easy as upgrading MacOSX, bit is not!

You better re install, many features have change on the new centos so many thing can broke if you upgrade, I recommend to set a new droplet with OS7 and move your site/app with out remove the old one, till you are sure is ready for production.
