So now I have Nof 12 and I'd like to completely redesign my site. But how do I copy a lot of the content from an old site to the new? This is just the text/data and not the design itself. I'd prefer not to try and change the existing site as I really want a clean start ( to try and free myself from years of poor choices and general clutter )

Only way I can think of so far is to publish the old site locally and open it in a browser or edit the actual files ( some are php ) and cut and paste from there. Is this the only option?
