I have a Wordpress blog on my server at home, running the latest Debian-maintained version in the 3.x series. I want to try my hand at virtualizing, and I'd like to do it on my blog, using the latest version downloaded from the site. I have read this post, but I want to clarify about different versions.
Is it recommended to upgrade in place (possibly breaking the Wordpress meta-package for Debian) then transfer, or should I transfer, then upgrade? In the latter, would I be able to just directly import a 3.x WP site, or do I need to find the old version, then update it after the data is transferred?
