Upgrade the Redis version of an instance

This page describes how to upgrade the version of a Memorystore for Redis instance. For a list of available versions, see Supported versions.

Caution: Upgrading an instance's version causes a connection reset for a couple of minutes or less, which makes the instance temporarily unavailable. Because of this reset, your application might fail to write or update a small amount of data. This can result in a stale or inconsistent cache while the instance is unavailable. You might also experience a delay of several minutes before core metrics appear. For more information, see About upgrading the Redis version of an instance.

Upgrading the instance version

Important: You can upgrade the version of an instance to any newer version. For example 3.2 to 7.0.

Console

1. Go to the Memorystore for Redis page in the Google Cloud console
   Memorystore for Redis
2. Click the instance ID of the instance you want to upgrade
3. In the Configuration section, next to Redis Version, click UPGRADE
4. Click the UPGRADE button in the dialog to upgrade your instance

gcloud

To upgrade the Redis version of your instance, enter the following command, replacing variables with appropriate values:

gcloud redis instances upgrade instance-id --redis-version=version --region=region

Where:

• instance-id is your instance ID
• version is the version you want to upgrade to:
  • Acceptable values are: redis_4_0, redis_5_0, redis_6_x, redis_7_0, and redis_7_2
• region is the region in which the instance is provisioned

For example:

gcloud redis instances upgrade myinstance --redis-version=redis_7_0 --region=us-central1
