And if anyone were to think that the Debian-style 'apt-get dist-upgrade' is the cure-all, there is a thread in the owncloud user mailing list that you may want to read, about an admin who locked up (and ended up losing) his owncloud instance after doing a dist-upgrade to Ubuntu 16.04 (he didn't specify the source version).....
You will always find examples of release upgrades going wrong. The Debian release notes[1] are very clear about the pitfalls of performing out such upgrades remotely in particular. My own experience has been more fortunate, as I have carried out multiple release upgrades over the years on many different machines. But I wouldn't dream of attempting the equivalent on a CentOS installation.
