Migrating an EC2-Classic cluster into a VPC

Note

We are retiring EC2-Classic on August 15, 2022.

Some legacy ElastiCache clusters on the EC2-Classic platform are not in an Amazon VPC. You can use the Amazon Web Services Management Console to move it into an Amazon VPC using the following steps:

Migrating an EC2-Classic Redis cluster into a VPC

Note

To determine if your cluster is on the EC2-Classic platform, see Determine the cluster's platform.

  1. You first need to create a Virtual Private Cloud (VPC). Follow the steps to create a VPC at Creating a Virtual Private Cloud (VPC).

  2. Once you have created the VPC, follow the steps to create a subnet group at Subnets and Subnet Groups.

  3. Your VPC comes with a default security group. You can choose to use it or you can create one by following the steps at Security groups for your VPC in the Amazon VPC documentation.

  4. In order to add your cluster to a VPC, you must first create a backup of it and then restore the backup into the VPC. Go to the ElastiCache for Redis console and choose your cluster. Choose Actions and then choose Backup. Enter a Backup Name and then choose Create Backup.

  5. Once the backup is created, you add it to the VPC you created previously. Return to the ElastiCache for Redis console and choose Backups. Choose the backup you created and then choose Restore.

  6. In Cluster name, enter a name for your cluster.

  7. In Choose a Subnet group, select the subnet group you created previously and then choose Continue.

Once the restoration process is complete, your cluster will be available in the VPC.

Note

Previous generation node types might not be supported on the VPC platform. For a full list of VPC supported node types, see Supported node types by Amazon Region.
