You must plan the upgrade of your StorageGRID Webscale system to ensure that the system is ready for the upgrade, and that the upgrade can be completed with minimal disruption.
Before beginning the upgrade from StorageGRID Webscale 10.4 to StorageGRID Webscale 11.0.x, or from version 11.0.x to version 11.0.y, you must read this guide in full and become familiar with the requirements and steps needed to upgrade your StorageGRID Webscale system.
Before you begin, be aware of the following:
- You must understand how your system will be affected during the upgrade to ensure you do not lose configuration changes, logs, or locally applied network changes. See "How your system is affected during the upgrade" for more information.
- You must understand the impact of the upgrade, so that you can update user accounts, groups, and tenant accounts appropriately after the upgrade is complete.
- You must have all materials required for the upgrade, including the StorageGRID Webscale upgrade files.
- You must be at version 10.4 or later to upgrade to version 11.0.x. If you have an earlier version, you must upgrade to version 10.4 before proceeding with the steps described in this guide.
- You must complete the upgrade on the same hypervisor platform you started with.
- You must upgrade all grid nodes for all data center sites from the primary Admin Node, using the Grid Management Interface.
- You must open port 9999 on all nodes. In StorageGRID Webscale 11.0, Admin Nodes use port 9999 to communicate with all nodes for Prometheus metrics. Some features will not work if port 9999 is blocked.
