Yes.  Retore both Wheezy systems from their respective back ups Then
read and follow the upgarde instructions which you should have done
first. And DON'T skip upgrading to interim releases to save time
thinking it's not necessary.  That piece of advice is in the
iinstructions, too, along with a lot of other wisdom to make your
upgrade as unproblematical as possible.
