This guide will help you upgrade from osTicket (which you already have installed in a directory on your self-hosted Linux server) to osTicket Awesome.
When your osTicket was first installed, you (or the person who installed it) chose a name for the directory that it was installed into. Common names that people use are osticket, helpdesk or support.
For the purpose of these instructions we will assume that your website is www.your-domain.com and that the support directory will be in your web root, thus your osTicket Awesome installation will be www.your-domain.com/support
(Your web root may be called public_html, www, httpdocs or something different depending on your web server configuration)
