A lot of your data is plain text, which you should be able to export or save as text. The other part is a hierarchical data base that cannot be read by another program. I recommend you make sure you have a printout of the entire data base. I recommend you break the project into two stages. In stage 1, I would enter the hierarchical data by hand from the printout into a new database. It sounds inefficient at first, but you will spend more time trying to resolve system incompatibilities if you try to export the hierarchical data. In stage 2, I would then use the text export to move the bulk of your data electronically. If you can afford a data entry clerk, the whole project should only take a few days.
