Jump Upgrade Procedure for Cisco Unified Communications Manager Release 4.1(3)–7.1(5) to 9.1(2)
If you are upgrading to Cisco Unified Communications Manager Release 9.1(2) from an older release and a direct upgrade from that release is not supported, you can follow the jump upgrade procedure. The jump upgrade procedure allows you to upgrade to an intermediate release on UCS hardware and then migrate to a virtualized platform. This document provides procedures for performing a jump upgrade to Release 9.1(2) using the following intermediate releases:
• 6.1(4) • 6.1(5) • 7.1(3) • 7.1(5)
The jump upgrade procedure supports the installation of these releases on UCS hardware for migration purposes only. Cisco does not support the production installation of these releases on UCS hardware or on any virtualized hardware.
