Download new version (Stable) of OSTicket from the downloads section of www.osticket.com. you will then take everything from within the upload folder and overwrite whatever is in your current OSTicket folder, then you go to your helpdesk system's URL and it will prompt you to update. however, I would make sure that any customization's done be documented because most likely it will get overwritten. @[deleted] am I correct as for the updating aspect from RC to stable?
