For a new Release 6.0 system, Cisco Unified MeetingPlace Audio Server software is installed in manufacturing, so you do not need to install Audio Server software.
For upgrades, if you have the Cisco Unified MeetingPlace Audio Server hardware and are using Audio Server Release 5.3 or 5.4 software, you must upgrade the software to Audio Server Release 6.0 yourself. (ACisco Unified MeetingPlace Audio Server system running version 5.3 cannot upgrade directly to Release 6.0. You must first upgrade to version 5.4, then upgrade to 6.0.)
