=head1 dada_archives_db_to_sql.pl

=head1 Description

C<dada_archives_db_to_sql.pl> migration script converts your Dada Mail List Archives from the Default backend, to one of the SQL backends. 

The Default backend for the List Archives is going to be a database file, like the Berkeley DB file format. 

C<dada_archives_db_to_sql.pl> is to be used I<after> you have reconfigured Dada Mail to use one of the SQL backends - you'll most likely do this via the Dada Mail installer. Once you have reconfigured your Dada Mail, none of your previous mailing lists will be available, until after you run this migration script. 

Before running this migration script, please make sure to backup your important Dada Mail files/information, most notably, the B<.dada_files> directory. 

=head1 Configuration

No configuration will need to be done in this script itself. The permissions of this script simply need to be set to, C<755>.

=head1 Using

Visit C<dada_archives_db_to_sql.pl> in your web browser, or run the script via the command line. Make sure to B<only run this script once>, or data will be duplicated.
