Solve the following python programming problem given the following code:
@ cli_app.command ('upgrade-db') 
@ click.option ('--config', default = 'config', help = 'Your application config file path') 
@ click.option ('--backup', default = 'no', prompt = 'Going to upgrade your DB to version 1.3.0, Did you backup your database?') 
def upgrade_db(config, backup) : 
    '
        Upgrade your database after F.A.B. upgrade if necessary (SQLAlchemy only)

        Version 1.3.0 upgrade needs database upgrade, read version migration on docs for
        further details.
