Update Debian Wheezy to Jessie

Last night I updated the system to Debian Jessie. This did not go without a struggle. But we are online again.

Upgrade Debian Wheezy to Jessie safely

First make a complete backup of your system. I use rsync for this and put the backup on a remote vps.

Make sure that your system is completely updated.

Update the sources.list for Jessie

After this run a update again

Okay now reboot (thumbs crossed)

You will probably encounter some problems. I had some problems with apache2, but after some searching, he is also up and running again.
