Upgrade planning and preparation

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.

Steps

  1. Estimating the time to complete an upgrade
    When planning an upgrade to StorageGRID Webscale 11.1, you must consider when to upgrade, based on how long the upgrade might take. You must also be aware of which operations you can and cannot perform during each stage of the upgrade.
  2. How your system is affected during the upgrade
    You must understand how your StorageGRID Webscale system will be affected during the upgrade.
  3. Impact of an upgrade on groups and user accounts
    You must understand the impact of the StorageGRID Webscale upgrade, so that you can update groups and user accounts appropriately after the upgrade is complete.
  4. Impact of an upgrade on tenant accounts
    Before upgrading to a new version of StorageGRID Webscale, you should understand how tenant accounts might be affected.
  5. Verifying the installed version of StorageGRID Webscale
    Before starting the upgrade, you must verify which version of the StorageGRID Webscale is currently installed.
  6. Obtaining the required materials for a software upgrade
    Before you begin the software upgrade, you must obtain all required materials so you can complete the upgrade successfully.
  7. Downloading the StorageGRID Webscale upgrade file
    You must download the upgrade file to a service laptop before you upgrade your StorageGRID Webscale system. If your StorageGRID Webscale system is deployed on Linux hosts, you must also download the StorageGRID Webscale installation files.
  8. Downloading the Recovery Package
    You must download an updated copy of the Recovery Package file before and after making grid topology changes to the StorageGRID Webscale system and before and after upgrading the software. The Recovery Package file allows you to restore the system if a failure occurs.
  9. Checking the system's condition before upgrading software
    Before upgrading a StorageGRID Webscale system, you must verify the system is ready to accommodate the upgrade. You must ensure that the system is running normally and that all grid nodes are operational.
  10. Managing legacy ILM rules
    ILM rules that were created using StorageGRID Webscale 10.2 or earlier were deprecated in StorageGRID Webscale 10.4 and are not supported in StorageGRID Webscale 11.1. If your StorageGRID Webscale system still includes these legacy ILM rules, you must recreate any that you still want to use. Then, you must delete all legacy rules before upgrading to version 11.1.
