The best strategy depends on the scope of your changes (were they
changes to the "look-and-feel" methods copied the DemoPortal
instance?  Did you modify the ZClasses in the PTKDemo product,
as well?)  One approach:

 * Create a CMFSite object alongside your DemoPortal instance,
   and use the ZMI's copy-paste to move all your customized
   DTMLMethods into the 'portal_skins/custom' folder of the
   CMFSite.  View the site -- does it look like what you expect?
   Fiddle with it, as a few names may have been changed "to
   protect the innocent".

 * If you cusomized Wizards, then you have a somewhat tougher
   row to hoe:  the CMF doesn't use them, preferring instead to
   create "empty" instances and then use the "normal" editing
   methods of the object to set metadata and add the content.
   Try adding a Document using the default mechanism, and see if
   it does what you want.

 * Browse the dogbowl site, http://cmf.zope.org, for details on
   the architecture of the CMF, and ask more questions here.

FWIW, your use case here is the driver behind the creation of
filesystem-based skins:  we needed to be able to deliver new
versions of the software without stepping on the community's
customizations.
