Upgrading from Single-AZ to Multi-AZ

Last updated: 2021-04-29 10:21:58

    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, click an instance ID/name in the instance list, and enter the instance management page.
    2. On the Instance Details tab, 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 completes 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 Configure > Add Replica in the Operation column.
    2. In the pop-up dialog box, 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.
