You need to make the class importable at the "old" location in order to
use instances of that class to convert to the new location.  Something
like::

 import persistent.mapping
 import sys
 sys.modules['Persistence.PersistentMapping'] = \
        sys.modules['persistent.mapping']

Then you should be able toload you old 'pages' object and create a new
one (using the new class) and copy the contents into it from the old one.
