I also had the idea that it 'was simple to renumber' untill someone pointed out to me that DNS + routers are not everything :( Especially But I do like Fred's point in making a procedure/document which at least documents all the points which one will come across when one is going to renumber. I think the identification of these points alone could be quite valuable. Thoug admittedly it all is quite based on which hard+software one is using and those can vary a lot. Greets, Jeroen
