And when you go wheezy->jessie->ascii, you'll end up with a lot of "undead" 
packages without upgrade candidate or things you put on hold ages ago:

$ apt-show-versions |grep --invert-match '\(uptodate\|not installed\|newer than 
version in archive\)'
$ apt-show-versions |grep --invert-match 'No available version'

And lots of configs of those:

$ dpkg -l|grep ^rc

You will most likely want purge all of them ... and probably shoot yourself in 
the foot on the way by removing :amd64 instead of the :i386 version, so keep 
your eyes open ;)
