Hmm, your export/import has already accomplished what the
method does (which is to make sure that the objects "know" about
the new location of their classes, which moved from PTKBase to
PTKDemo).

The method is intended for use in the case where you have upgraded
a portal instance "in place".  I would venture that export from old
import into new is actually a cleaner solution.
