downgrade from Woody to Potato

[Stephan Engelke <engelke@gmx.net>]

Hi everyone,

this question has been asked before, but I could  not get any working
results.  After installing Woody a couple of days ago, I'd like to
downgrade to Potato again.  Is there a way to do this without
reinstalling the system? 

Reactivating the potato entries in /etc/apt/sources.list and deleting
the woody ones did not help.  apt tells me that my system is up to
date ;-)

Cheers -- Stephan
