I’ve switched from my two three years old dedicated servers to one brand new virtual server. Reasons are : These servers costed me too much and they were becoming old (risk of failure increases). It wasn’t worth it.

I spent last night doing that because I didn’t want to interrupt anybody using these servers.

My two servers were running some Debian and I’m now switching to a CentOS virtual server. I was a little bit worried at first that CentOS would have a crappy package management system, but its yum is in fact working the same way as Debian’s apt-get and OpenSuse’s zypper. The oool thing is that these three package management systems roughly work the same way : install , you don’t have to learn a new “ultimate” way to upgrade your software (like on FreeBSD). By the way, the faster package management system is yum, and the slowest one is zypper.

The biggest problem I had so far was to move all the databases. Previously, I was always using some Debian hosts, I was using exactly the same version of MySQL, so I just had to copy the MySQL datadir and logs files. Here, I had to export/import everything.

CentOS has an antique 1.2.4 version of Mono (when the current version is 2.4). I couldn’t manage to compile from the tarball but compiling from the SVN worked fine.
