Make a backup first! I'm not sure that it won't break during an upgrade of OS. Sentora is made to install on 14.04, but it makes it's configs on the fly during install depending on OS requirements. I tried a 12.04->14.04 upgrade with Sentora installed and it was not fun. I had to answer a LOT of questions during the upgrade and Sentora did not work after doing so. (Although I may have missed some of the questions.)
Some of the questions had to do with keeping original configs or replacing with newer.
After all that mess, I would suggest back everything up, install fresh 14.04, then re-install Sentora and then add the sites/databases from your backup.
