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

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.

Thanks !!! And if everything is working then i can make a copy of it and move it to my other droplet. Because i don’t want change the IP numbers of my websites, email A records etc…

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!
