I checked similar question here but not got an answer. I upgraded to elementary os from ubuntu 16.04 and now want to migrate it back. Have anyone successfully done so?
Update: I don't know exactly how it got upgraded from ubuntu 16 to elementary os loki. I was just tryining pantheon-desktop . After installing I remember did apt dist-upgrade and magically had elementary os loki name writter in my next reboot instead of ubuntu 16
