Migrating WordPress from a shared hosting environment to a virtual private server

November 9, 2011

I was migrating this WordPress blog early this morning from Bluehost to a dedicated Rackspace Cloud Server that I’m already using for a web application I’m writing. It was almost painless! Just ran into a few minor post-migration issues.

The reason I’m migrating is mainly because I want more control, like being able to use my own self-signed SSL certificate without paying extra, for example. I figured since I’m getting very low traffic it really …
