Updating Using the Server Installer

Please follow Updating from MU/Build to Build for a detailed guide to the update procedure. This page only contains a subset of the required steps!

This page describes how to update the Dispatcher Paragon installation using the server installer. This procedure is valid for First Server, Additional Management Server, and Site Server deployments.

The minimum free space required for the update is 8.8 GB.

General Information

  • The installer detects the previous installation and informs the user that an update instead of a clean installation will be performed.

  • The update does not allow the changing of any system configurations, it updates the environment as-is.

The update procedure can be summarized as several steps:

  1. The installer stops all running services.

  2. The new version is deployed.

  3. A configuration that may contain user data is restored.

  4. Services are started again.

Order of Update

  1. Update Management Server or one of the Management Server cluster nodes first.

    The first update updates the database, therefore, it is no longer expected to work with the previous version of Dispatcher Paragon Management Services.

  2. Update the remaining Management Server cluster nodes one by one (i.e., start the update of the second node after the update of the first node has finished).

    Do not start Management Services manually before all nodes have finished updating.

  3. Update Site Servers after the update of Management Server(s) is finished.
