Edit online

OVERVIEW

Edit online
The IBM SevOne Network Performance Management (NPM) 7.2 contains the following components.
  • SevOne NMS
  • SevOne Data Insight
  • SD-WAN
  • SDN
  • Wi-Fi
Note:
  • To upgrade to SevOne NMS 7.2.0, the minimum mandatory version you must be on is SevOne NMS 7.0.1 or above. If you are on a version prior to SevOne NMS 7.0.1, please refer to Upgrading SevOne NPM to 7.0.x from Previous Versions.

  • To ensure the smoothest upgrade and not interrupt your user’s productivity, do not initiate your upgrade until you have reviewed all deprecations for each release you pass through on your upgrade path to 7.2. Deprecation notices are communicated in the IBM’s Release announcements. Please sign into the IBM Support Portal and subscribe to IBM SevOne NPM.

  • To complete your upgrade, all components must be on the same version. IBM supports one version back for the purpose of performing upgrades.

    • Not all features will be enabled until components are on the same version.
    • Some features will not work unless the components are on the same version.

  • Order of Upgrades
    When multiple components of SevOne NPM are involved, the Solutions components (SDN, SD-WAN, and Wi-Fi) must be upgraded first followed by SevOne Data Insight and then, SevOne NMS.

If you have any doubts, please reach out to SevOne Support or Expert Labs for guidance before initiating the upgrade.
