I can help.
Doing a live upgrade from debian 6 (Squeeze) to debian 7 (Wheezy) is not a smooth upgrade as previous upgrades were.
So if you want to upgrade a live server contact me… sgrayban @ gmail.com
Debian Squeeze will be discontinued Dec 2013
just to confirm: I recently upgraded from squeeze to wheezy, and things were NOT smooth at all - I had to re-install and reconfigure a ton of things, and it was really painful…
Correct which is why I offered this service because I wrote my own scripts to fix the broken configurations and/or missing debs.
I DO NOT recommend anyone doing the upgrade from 5 to 7 or even 6 to 7… There is a high chance you can ruin your live server. Leave this to the pro’s…
