# Tasks can fall through the gaps when matching on '='

#      it would not match due_today or due_tomorrow, hence would not appear in Fat Free.

1. Create a text backup of your data form the live server.  This will ask for a password.

    mysqldump -u your_user -p your_redmine_database > backup_sql_file.sql

2. Transfer the backup_sql_file.sql to your new server.

3. Once there, drop the existing database on the new server and import your database to the empty database on the new server.

    !!!! Triple check this is on the new server and not your live one!!!!

Surround a heredoc with quotes and you can continue the code on the same line:

    render :status => 404, :text => <<-'EOH' and return unless setup
        article not found<br/>
        I, as a server, have failed<br/>
        https?
        EOH

Quotes also give you more freedom/creativity with the terminal ID:
