 #-----------------------------------------------------------------------------
 #   convert change request data from a Flat File from a Legacy sys to RT.
 #   Turn OFF RT and then change your RT_SiteConfig.pm to turn off logging.
 #   Be sure to TURN OFF all scrips either before being RT down or via DBA/SQL.
 #   scrips will try to run and logging will make the program run FOREVER!!
 #   flat file input can be created by via Data::Dumper;
 #   Obviously, field names will be different. OUR Data Names are all CAPS_CAPS
 #   We built tickets, CF's into two different queues, ES-HRIS & ES-LETS
 #   We also have an extra Ticket Status value of "QA testing".
