When you switch a Redis instance from classic network to Virtual Private Cloud (VPC), the classic network endpoint is retained temporarily so your application can continue connecting while you update its configuration. Once your application is fully migrated to the VPC endpoint, release the classic network endpoint to clean up the connection.
Prerequisites
Before you begin, ensure that:
The instance has a retained classic network endpoint. This endpoint exists only if the instance was previously switched from classic network to VPC. For details, see Switch the network type of an instance from classic network to VPC.
Your application is already using the VPC endpoint. The classic network endpoint becomes unavailable immediately after it is released.
Update your application's connection string from the classic network endpoint to the VPC endpoint before proceeding. Releasing the classic network endpoint takes effect immediately.
Release the classic network endpoint
Log on to the console and go to the Instances page. In the top navigation bar, select the region where the instance is deployed, find the instance, and click its ID.
In the Connection Information section, click Change Expiration Date next to Classic Network Access.
In the dialog box, select Release Now.
Click OK.
The classic network endpoint is released immediately and can no longer be used to connect to the instance.
