[Setup] Unable to migrate Data.fs from 2.5.2 to 3.2.2

[DownNotAcross]

This keeps getting more and more twisted, and I hope this post actually makes
it through the convoluted process of getting subscribed to the mailing list
via the forum...

Anyway, I have an older server running Plone 2.5.2.  I need to migrate the
data from this server to a new server running 3.2.2.  The OS is CentOS 5.2.

I attempted following the instructions posted here:
http://plone.org/documentation/how-to/move-site - first off, I had to take
the contents of "products" out of the way as that was confusing things even
further.  So, working with just Data.fs, I did the following:

1) Rename the "out of the box" Data.fs to Data.fs.orig.
2) Copy the Data.fs from the old server in its place.
3) Confirm permissions and ownerships are the same as for original Data.fs
4) plonectl start.

After step 4, I'm unable to connect and get a 502 proxy error.  Tried
starting in debug mode as:

plonectl stop
plonectl zeoserver start
plonectl client1 fg

I noted that zeoserver started, and upon grep'ing for the PID that was
reported when it started, I see that it's running.  buildout.cfg has it on
port 8100.  If I do lsof -i:8100, there is NOTHING running on that port. 
The debug output from client1 is below:

   1.
      # ./plonectl client1 fg
   2.
      client1: /usr/local/Plone/zeocluster/parts/client1/bin/runzope -X
debug-mode=on

... and so on.

If I move the old Data.fs (the "out of the box" clean install one) back into
place, it starts fine without any errors.

I'm completely lost and also completely new to this monster known as
Plone... any help would be greatly appreciated.

Thanks
