Ghost has released 1.0, with breaking changes so there’s no smooth upgrading method but to take a fresh install. Here’s my migration of this blog to Ghost 1.0. There’s already an official tutorial to help you walk this through, but since it only supports Ubuntu officially, so I have to explore my own way on my CentOS 7 server. It turns out that there’s not much modifications compared to Ubuntu version, so I’m just writing this down as a record of my migration.
