Make a file copy of the 2.0 database (while the 2.0 service is
stopped) and put it on a 1.5.2 server. Then use gbak on the 1.5.2
server to backup the database, then use gbak on the 1.5.2 server to
restore it to the 1.5.2 server. Then you can connect to that restored
database from the 1.5.2 server.

You can only do this if you haven't used any of the new FB2 specific
features in the database (obviously).
