Important
Users wishing to upgrade from version v8.0.x onward should follow the following process :Patch Moogsoft Enterprise
Saas customers can contact support to request an upgrade, see Upgrading and Updating Your Moogsoft Hosted Instances.
For information on how to upgrade from other versions, see Moogsoft Releases.
For instructions on how to install a distributed high availability (HA) configuration, see Fully Distributed HA Installation.
Your upgrade path depends on your preferred mode of deployment:
RPM: Use this method if you have root access to your Moogsoft Enterprise servers and you do not want to change the default installation locations.
Tarball: Use this method if you need to run the process as a non-root user, or you want the ability to deploy to a non-default location and install all components under one directory.
The Tarball installer is hosted on the Moogsoft "speedy" Yum repository: https://speedy.moogsoft.com/installer/. Contact Moogsoft Support for access if you do not already have an account.
If you have root access but your Moogsoft Enterprise servers do not have access to the internet, see "Prepare for an offline upgrade" in RPM - Prepare to upgrade.
Your Moogsoft Enterprise deployment is broken up into a set of roles. A role is a functional entity containing components that should always reside on the same server:
UI: Nginx, Apache Tomcat, UI integrations.
Core: Elasticsearch, Moogfarmd, RabbitMQ, Events Analyser.
Databases: MySQL, Moogsoft Enterprise databases.
Data ingestion: Server side LAMs.
This process enables you to upgrade the components in each role, whether your Moogsoft Enterprise system is distributed on several servers or installed on a single host.
Note
The implementation of a new Topology API means any old topologies are removed as part of the upgrade. It is important that any recipes using topology in any way are updated once the topologies have been recreated in v8.x.x post-upgrade, before events are sent into MoogFarmD.
Hop limit has been removed from Recipe configurations in Moogsoft Enterprise v8.0.0. You can reconfigure a hop limit if you are using a named or inferred Topology to filter a Recipe.
