Foglight 5.9.4 - Upgrade Guide

Upgrade use cases

The following are common upgrade use cases:

Scenario 1 — New release

You notice that there is a new version of Foglight and are wondering if you should upgrade. If you do not have a specific reason to upgrade, we recommend you stay on the version you are running now.

Scenario 2 — New Management Server features or defect fixes

A new release of Foglight typically delivers new features and defect fixes. See the Foglight Release Notes for information about new features and defect fixes. We recommend the Management Server upgrade to customers who want one or more of the features or defect fixes in a new release.

Customers who want to take advantage of new features and defect fixes can do so with a simple upgrade to the Management Server. This upgrade is expected to take 15 minutes or less. An upgrade to the server does not introduce any incompatibilities with earlier versions of other Foglight core components; therefore, with the Management Server 5.9.x upgrade, you should not have to upgrade any other components in your environment.

Scenario 3 — Agent Manager client-side feature dependency or defect fix

A new release of the Agent Manager typically delivers new features and defect fixes. For information about new features and defect fixes, see the Foglight Agent Manager Release Notes. Customers who want to take advantage of a new feature or defect fix may consider a move to the latest Agent Manager client.

The 5.9.x Agent Manager Adapter is updated as part of the Management Server 5.9.x upgrade, and the new adapter is backward compatible with all earlier versions of the Agent Manager.

Generally, there is no need to upgrade the client side of the Agent Manager. An Agent Manager client-side upgrade is required only in the following situations:

You do not need to upgrade all Agent Manager clients to the latest version. You only need to upgrade the ones that meet one or more of the conditions specified above.
