Upgrade Ops Manager with an rpm Package

On this page

This tutorial describes how to upgrade an existing Ops Manager installation using an rpm package.

Upgrade Path

The version of your existing Ops Manager installation determines the upgrade path you must take to upgrade to Ops Manager 3.6 or later.

Important

  • You must follow the upgrade path for your existing version to perform necessary database migrations.
  • To protect your data, Ops Manager refuses to start direct upgrades from versions 1.8.x and 2.0.x to version 3.4 or later.
  • In high availability environments, you must shut down every Ops Manager application server before starting any Ops Manager application servers upgraded to the new version.

The following table lists upgrade paths for all versions:

Existing Version Upgrade Path
3.6.x Use this tutorial to upgrade from Ops Manager on 3.6.x to a more recent 3.6.x version.
3.4.x Use this tutorial to upgrade from Ops Manager 3.4.x to version 3.6.x.
2.x

  1. Upgrade from Ops Manager 2.0.x to version 3.4.x. For the specific upgrade path for your version, refer to :v3.4:`v3.4 upgrade documentation </tutorial/nav/upgrade-application>`.

  2. Ensure that your deployment has fully migrated to 3.4 before upgrading to 3.6. To verify:

    1. Click the Admin link in the top right corner of Ops Manager.
    2. Go to General > Ops Manager Config.
    3. Click Miscellaneous tab, and scroll to Ops Manager Data Migration section. If the displayed status is Migration is Complete, you may upgrade to 3.6

    For more information, see Ops Manager Data Migration.

  3. Use this tutorial to upgrade from Ops Manager 3.4.x to version 3.6+.
1.8.x or earlier
  1. Follow the appropriate upgrade path to upgrade your version to 2.0.x. For the specific upgrade path for your version, refer to :v2.0:`v2.0 upgrade documentation </tutorial/nav/upgrade-application-daemon>`.
  2. Upgrade from Ops Manager 2.0.x to version 3.4.x. For the specific upgrade path for your version, refer to :v3.4:`v3.4 upgrade documentation </tutorial/nav/upgrade-application>`.
  3. Use this tutorial to upgrade from Ops Manager 3.4.x to version 3.6+.

There are no supported downgrade paths for Ops Manager.

Important

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

Advisories

Upgrading to Ops Manager 3.6

Before upgrading Ops Manager from 3.4 to 3.6, complete the following actions:

  • Upgrade all backing databases to MongoDB 3.2 or later.

  • Wait for Ops Manager to finish upgrading the monitoring schema.

    To monitor the schema upgrade:

    1. Click Admin.

    2. Click Ops Manager Config.

    3. Click the Miscellaneous tab.

      The progress should be shown before the Default Monitoring Data Retention heading.

  • Change mms.minimumTLSVersion if you must support older TLS versions.

    Ops Manager Application supports TLS 1.2 only by default.

    To re-enable ciphers which have been disabled, change mms.disableCiphers.

    Warning

    Consider the security implications carefully before doing this.

Prerequisites

Hardware and Software Requirements

Your servers must meet the Ops Manager System Requirements.

Warning

Failure to configure servers according to the Ops Manager System Requirements, including the requirement to read the MongoDB Production Notes, can lead to production failure.

Administrator Privileges
You must have administrator privileges on the servers on which you perform the upgrade.
Download Link
You must have the download link available on the customer downloads page provided to you by MongoDB. If you do not have this link, you can access the download page for evaluation at http://www.mongodb.com/download.

Procedure

Important

Before you perform the upgrade procedure, ensure that you have a current backup of the Ops Manager backing databases. To perform a full backup, see Shut Down and Back Up Ops Manager.

1

Stop all existing Ops Manager services.

For platforms that use systemd (RHEL, CentOS, SUSE12):

copy 
sudo service mongodb-mms stop

For platforms that use SysVInit (Amazon Linux):

copy 
sudo /etc/init.d/mongodb-mms stop
2

Download the latest version of the Ops Manager package.

  1. In a browser, go to http://www.mongodb.com and click on the Download button.
  2. Complete the form.
  3. On the MongoDB Download Center page, click on the Ops Manager tab.
  4. Select RedHat 6+ / CentOS 6+ / SUSE 12+ / Amazon Linux from the Platforms drop-down menu.
  5. Select RPM from the Packages drop-down menu.
  6. Click Download.

Note

The downloaded package is named mongodb-mms-<version>.x86_64.rpm, where <version> is the version number.

3

Install the Ops Manager package on each server being used for Ops Manager services.

Install the .rpm package on each Ops Manager Application server by issuing the following command, where <version> is the version of the .rpm package:

copy 
sudo rpm -Uvh mongodb-mms-<version>.x86_64.rpm

The installer preserves the existing conf-mms.properties configuration file and names the new configuration file conf-mms.properties.rpmnew. Both are located in /opt/mongodb/mms/conf/.
