Retirement of classic network for PolarDB

Since Alibaba Cloud launched its public cloud services in 2011, the classic network architecture has provided foundational network support for countless customers. In 2014, we introduced cloud products based on VPC to offer a more secure, stable, flexible, and high-performance option. After years of development, the VPC architecture has become the default choice for most cloud users. Therefore, PolarDB will officially begin retiring PolarDB clusters that run on the classic network.

To minimize the impact on your workloads, Alibaba Cloud provides a generous timeline to plan, test, and execute your migration to VPC. We will also provide tools, documentation, and professional support to assist you throughout the migration process.

Note

PolarDB clusters already in a VPC are not affected. You can continue to use them without interruption.

Timeline and impact

Starting 00:00 on October 30, 2024: Suspension of cloning, renewals, and configuration changes

You will no longer be able to clone, renew, or change the configuration of PolarDB clusters in the classic network. Renewals will also be disabled for all subscription PolarDB clusters in the classic network.
Starting 00:00 on February 28, 2025: End of service

PolarDB clusters in the classic network will be forcibly shut down and released. This affects the following clusters:
- Expired subscription PolarDB clusters.
- pay-as-you-go PolarDB clusters.
Note
Subscription PolarDB clusters in the classic network that have not expired will not be forcibly shut down or released. You can continue to use them as usual. However, because renewals are disabled, migrate to a VPC as soon as possible to prevent service disruption. For instructions, see How to migrate affected classic network PolarDB clusters.

Identifying all affected classic network PolarDB clusters

Using OpenAPI

For PolarDB-X 1.0 instances, you can call the DescribeDrdsInstances operation to query cluster information. If the NetworkType parameter in the response is set to CLASSIC, the PolarDB cluster is in the classic network.
Using the console
1. Log on to the PolarDB-X 1.0 console.
2. In the top navigation bar, select the region where the instance is deployed.
3. In the left-side navigation pane, click Instances.
4. Click the PolarDB-X 1.0 tab and check the Network Type of the instance. In the instance list, instances with classic network in the Network Type column are affected.

Migrating affected classic network PolarDB clusters

You can switch a PolarDB cluster to a VPC and vSwitch. This allows clients to communicate with the PolarDB cluster within the same VPC, which improves security and lowers network latency. For instructions, see and Switch the network type of a PolarDB-X 1.0 instance to VPC.
