[Setup] Migrating from Plone 2.1.3 to 2.5.5 in hopes of eventually hitting 3.1.7

[Irfon-Kim Ahmad]

I'm having some trouble migrating our Plone 2.1.3 site to current.

At first, I tried migrating step by step.  Migrating from 2.1.3 to 2.1.4
worked fine.  However, I couldn't seem to get anywhere from there, and I
read some articles online that indicated both that 2.1.4 was a bit of an
evolutionary dead end and that I might as well try to go from 2.1.3 to
2.5.x.   When I say 2.5.x, I've tried 2.5, 2.5.1 and 2.5.5 for all of
these tests.  Currently, I am trying to go 2.1.3 -> 2.5.5, as many of
the 2.5.x change logs up to and including that version mention
improvements to the migration code.

My starting conditions are:

Zope: 2.9.3
Python: 2.4.3
Plone: 2.1.3
PIL: 1.1.5

I seem to get the same results whether I upgrade Plone to 2.5.5 first
then Zope to 2.9.8 or vice versa.  My current ending conditions are:

Zope: 2.9.8
Python: 2.4.3
Plone: 2.5.5
PIL: 1.1.5

This all shows up fine when I go to the Site Setup page within my Plone
site, which also seems to work fine.  However, when I go to the home
page of my site, I get an orange error box in the top left just below
the header bar saying:

Error exceptions.KeyError on here/portlet_navigation/macros/portlet:
'children'

An orange error box in the bottom left saying:

Error exceptions.AttributeError on
here/portlet_plone_navigation/macros/portlet: portlet_plone_navigation

...and no content at all in the body area.  (The title shows up in the
title bar fine.)

This happens even if I go to sub-pages.  All the content and pages show
up in the ZMI (I get the same results if I go to their View tab, but
they're there, anyway) if I go there and try to sort of browse the
content tree, so the data appears to still be in the database.

Any help would be greatly appreciated. I'm doing this on a clone of the
production server and I've backed up all the relevant folders six ways
to Sunday, so I should be able to roll whatever back to whenever and try
any experiments you'd like me to try.  I've tried a bajillion
combinations of things with always more or less the same end result
(well, exporting and importing failed in more fundamental ways), so I'm
a little at a loss now. 

When I did the migration from 2.1.3 to 2.5.5, these are the messages
that I got:
