[Zope] Zope 2.0.1 export

Hi, I have an old linux system running a document store I wrote some time ago in Zope 2.0.1. I've tried exporting my document store but cannot seem to get it re-imported into the latest version of Zope. I can ftp the documents out, but of course lose all the information about each document. Does anyone have any ideas on how to get this working ? Kind Regards Paul Gresham
