Upgrading to Multi-AZ Deployment

Last updated: 2021-07-08 15:15:31

    This document describes how to upgrade instance deployment from single-AZ to multi-AZ in the TencentDB for Redis console.

    Step 1. Upgrade the Redis version to support multi-AZ deployment

    1. Log in to the TencentDB for Redis console and click an instance ID in the instance list to enter the instance management page.
    2. On the Instance Details page, click Upgrade to Support Multi-AZ Deployment next to AZ.

      The upgrade will migrate only the metadata but not the business data. Usually, the upgrade can be completed in 3 minutes.

    Step 2. Add replicas to replica AZs

    1. Log in to the TencentDB for Redis console, locate the desired instance in the instance list, and select Configuration Modification > Add Replica in the Operation column.
    2. In the pop-up window, specify replica AZs, and deploy the master node and replica nodes to different AZs.

      Currently, the replicas of a multi-AZ deployed instance cannot be deleted.
