Upgrade Ops Manager on Microsoft Windows Server

This tutorial describes how to upgrade an existing Ops Manager installation on Microsoft Windows.

Upgrade Path

The version of your existing Ops Manager installation determines your upgrade path. The following table lists upgrade paths per version:

Existing Version Upgrade Path
2.0 or later Ops Manager supports direct upgrades from version 2.0.x. Use this tutorial to upgrade directly to 3.4.0.
1.8 or earlier
  1. Follow the appropriate upgrade path to upgrade your version to 2.0. For the specific upgrade path for your version, refer to :v2.0:`v2.0 upgrade documentation </tutorial/nav/upgrade-application-daemon>`.
  2. Once upgraded to 2.0.x, use this tutorial to upgrade to 3.4.0.

There are no supported downgrade paths for Ops Manager.


It is crucial that you back up the existing and gen.key files because the upgrade process will delete existing data.

Release Advisories for Ops Manager 3.4

Before upgrading Ops Manager from 2.0.x to 3.4, complete the following actions:

  • Upgrade backing databases to at least MongoDB 3.0.8. MongoDB 2.6 is no longer allowed as a backing store.

  • Ensure the data partitions for the Ops Manager Application Database have at least 50% free disk space.

    Once the Ops Manager upgrade to 3.4 completes, Ops Manager begins migrating of all monitoring data to a new schema in the background. This migration requires significant free disk space.

  • Add necessary IP addresses or CIDR blocks for to the whitelists for any API clients connecting to the Automation configuration endpoints.

  • Back up the mms.conf file in your current installation if you have modified it.

    This is not a regular practice as mms.conf contains platform and network administration settings for Java VM and Ops Manager network port settings. You must use the new mms.conf file the upgrade installs. Reapply any modifications from your backed up copy to the new mms.conf after completing the upgrade.
