A complete checklist for upgrading platform components   NOTE: The information in this article is not release-specific. You can reference it for any release. To make sure you complete all the tasks necessary for upgrading platform components after a release, we recommend following the upgrade checklist instructions below.    Table of Contents Prepare to upgrade your platform components Plan your platform component upgrade  Step 1: Upgrade the Enterprise Console Step 2: Upgrade the Events Service Single-node install or manual upgrade? Step 3: Upgrade the EUM Server Step 4: Back up the Controller Step 5: Upgrade the Controller with the Enterprise Console Troubleshooting Additional Resources   Prepare to upgrade your platform components Review the Product Announcements and Alerts page for details on any intermediate versions between the current version of your instance and the version you are targeting. Review either of the following to confirm the compatibility of the various components of your AppDynamics environment: Knowledge Base article: How do I get started with upgrading my AppDynamics components for any release? , especially the component compatibility matrix Technical documentation: Agent and Controller Compatibility   Plan your platform component  upgrade Before upgrading to a newer version of the platform, complete the tasks outlined in the Update Product Components  documentation. To ensure all data is transferred properly, perform your upgrades in the specific recommended order for the components you’re using:   Step 1. Upgrade the Enterprise Console Start with a review of the Upgrade the Enterprise Console documentation.   To determine the requirements, review the Controller system requirements and increase your hardware resources if necessary.   Step 2. Upgrade the Events Service   Do I need a single node install or a manual upgrade? The Enterprise Console supports the installation of the Events Service on a Windows environment for a single node install . If you have several remote nodes, you will need to do a manual upgrade of the Events Service cluster and set the keys manually. For instructions on connecting to the Events Service, see the End-User Monitoring Connection Settings  documentation.   Note: Even though th e Enterprise Console will set and sync the keys between the Controller and Events Service, we still recommend confirming that the keys were synced correctly: appdynamics.on.premise.event.service.key == ad.accountmanager.key.controller Note: If you're upgrading the Events Service using the Enterprise Console, you don't need to stop the Events Service.   Complete the Events Service upgrade Follow the Upgrade the Events Service documentation to complete the Events Service upgrade.   Step 3. Upgrade the EUM Server See Upgrade the EUM Server for instructions on upgrading an EUM Server.   Step 4. Back up the Controller Complete a full backup of the Controller. Refer to  Back up the Existing Controller for instructions.   Step 5. Upgrade the Controller with the Enterprise Console   Final Upgrade Considerations Before completing the upgrade process, review the following and implement as appropriate:   Upgrading an HA Pair If you're upgrading an HA pair, we recommend upgrading via CLI using the phased upgrade method (new in v4.5.6) . This allows you to retain the Controllers' HA roles so that the primary and secondary roles do not switch after the upgrade.   You can also check the status of your primary Controller before upgrading the secondary.  If you encounter any issues during or post-upgrade, you can roll back by promoting and failing over to the preserved, secondary Controller.    Though we recommend the phased upgrade method, it is also possible to use GUI or the old CLI method to upgrade your HA pair.   Upgrading from a small to an extra-large deployment You can directly upgrade from small/demo deployments to large/extra large deployments. See the Tuning for Large Profile Controller documentation for instructions on preparing a large deployment.   Be sure to check the Controller’s database.log Check the Controller&rs database.log for any errors during this process. You can find the log at <controller_home>/db/logs/database.log> . There should not be any InnoDB: Error lines in the log from the last startup. If any errors are found, contact AppDynamics Support before attempting the upgrade. Upgrading the Controller with a corrupt database may put the Controller in a bad state with a high recovery time.   Upgrade the Controller with the Enterprise Console Once you’ve resolved the preceding considerations and completed the outlined steps, refer to the Upgrade the Controller using the Enterprise Console  documentation to perform and complete the upgrade.   Troubleshooting In the event of an error condition, follow the troubleshooting steps in the Troubleshoot the Upgrade documentation.  If you experience an error condition when upgrading a platform component, please go to  www.appdynamics.com/support, scroll to the AppDynamics Support section, and click Support Portal.         Additional Resources How do I get started with upgrading my AppDynamics components? ...
