You can't downgrade the version of a Memorystore for Valkey instance.\n\n- Before you run a version upgrade operation, we recommend that you [create a backup](/memorystore/docs/valkey/manage-backups#create-on-demand-backup) of your\n instance's data.\n\n- To increase the speed and reliability of the version upgrade operation,\n upgrade your instance during periods of low instance traffic. To learn how to\n monitor instance traffic, see [Monitor instances](/memorystore/docs/valkey/monitor-instances).\n\n- Make sure that you use our [best practices](/memorystore/docs/valkey/general-best-practices#memory_management_best_practices) for memory management\n to manage the memory of your instance.\n\n- Before you upgrade the version of your instance, make sure that you [become\n familiar with the newer version](/memorystore/docs/valkey/supported-versions)\n to see how this version impacts your application.\n\nVersion upgrade behavior\n------------------------\n\nMemorystore for Valkey upgrades the version of your instance by updating\nall nodes within the instance. This upgrade process is similar to a maintenance\noperation. For more information about the process, see [Create-before-destroy lifecycle strategy](/memorystore/docs/valkey/about-maintenance#create-before-destroy_lifecycle_strategy)."]]
