I decided to upgrade my Sun Ray servers from 4.x version to 5.x. Upgrading Sun Ray server after 4.x version release, Oracle made it easy to accomplish this task with minimum effort even effortless would be better word to use. Since oracle has excluded firmware package from Sun Ray software bundle and named it Sun Ray Operating Software, you should have to download it from https://support.oracle.com prior to install/upgrade Sun Ray Software 5.x
Prerequisites:
- Download Sun Ray Operating Software from https://support.oracle.com
- Download Sun Ray Software 5.x from https://support.oracle.com, https://edelivery.oracle.com
- Copy Sun Ray Operating Software to Sun Ray Server’s /Desktop directory
- Copy Sun Ray 5.x Software to Sun Ray Server’s /Desktop directory
