Description: Debian GNU/Linux 7.0 (wheezy)
I’ve spent the last 30 minutes (more or less) in the upgrade of my VPS from Debian 6 to Debian 7, in short this has been a great success just 1 conflict with some packages and some old WordPress module of another website that are not compatible with php 5.4, total downtime of the website : 8 minutes.
