Did something similar myself a while ago.

Assuming the pages were all generated from a template originally, I found
the following the simplest.

Construct your database structure, create some test data.
Create output system (db=>xml=>html whatever)
Build a (set of) perl script(s) to parse the HTML and strip the data out (if
your pages are anything like mine, they're not *identical* formats so you'll
end up needing something custom-built).
Push the data into PostgreSQL.
Publish the website from the database
Run a "diff" of the old and new pages
Tweak system as required and repeat until satisfied everything works.

The key problem I found was that unless the pages were generated from a
database to start with, they all seemed to have minor changes. The only way
I could be satisfied I'd not missed data was to publish and compare. The
first couple of "diff"s were scary, and I ended up cutting and pasting a few
pieces manually, but I got everything out.
