Unified Node Topology: Upgrade a Multinode Environment with the ISO and Template

Note

  • When upgrading from VOSS-4-UC 18.1.3, refer to Upgrading from 18.1.3 to Current Release - Summary.

  • Upgrading to release 21.1 requires a system on 19.x, with security updates completed. The upgrade includes:

    • an upgrade to the underlying operating system to Ubuntu 18.04.4.

    • the installation of a new cluster check command available from the 21.1 ISO by running app install check_cluster.

  • While template installation and system upgrade takes approximately two hours at a single site, this may vary in accordance with your topology, number of devices and subscribers. Adjust your upgrade maintenance window to allow for your configuration.

    You can follow the progress on the Admin Portal transaction list.

  • When upgrading from CUCDM 11.5.3 Patch Bundle 2 or VOSS-4-UC 18.1 Patch Bundle 2 and earlier, re-import specified CUC models according to your current version. Refer to the final upgrade procedure step.

  • Tasks that are marked Prior to Maintenance Window can be completed a few days prior to the scheduled maintenance window so that VOSS support can be contacted if needed and in order to allow for reduce down time.

  • If any Microsoft integrations exist in VOSS Automate pre-upgrade, then the existing device connections configured for Azure AD Online will not be automatically migrated to MS Graph and will have to be manually migrated to MSGraph prior to the upgrade to 21.3.

    Service Providers who are operating with release 19.3.4 of the Cisco-Microsoft Adaptation should contact VOSS Global Services first.

    The MS Graph connection configuration requires additional details, which must be obtained prior to upgrade. Please see the VOSS Automate Configuration and Sync and Microsoft Configuration Setup topics in the Core Feature Guide.

    • Ensure MicrosoftTenant, MSTeamsOnline and MSGraph instance have the same name by renaming instances.

  • If you have FIPS enabled on your system, the before continuing with the upgrade, see:

    Upgrading from Release 19.3.x with FIPS enabled.
