You place a file config/storage/databases/mysql.xml (take it from
mmbase.jar), and add:

 <option name="database-stores-binary-as-file" />

In 1.7 it is similar, but you have to place it somewhere under WEB-INF/classes
(to hide the one in the mmbase.jar).

Then, restart, and go to the admin-pages mmbase/admin->admin->blobs and
click on the 'convert' button. Then cross your fingers. If step 1 did not
succeed it will report that the database is not configured for blobs on disk.

After that, check if images and attachments are still working. If
everything seems ok (also try to create news ones and so on), you can alter
your tables (drop the handle fields).

I've done it a few times, though perhaps not with 1G with data.
