Starting March 01, 2021, Alibaba Cloud no longer provides updates or maintenance for the minor engine versions of ApsaraDB RDS instances that run MySQL 5.5. Only technical support is provided. If your RDS instance runs MySQL 5.5, we recommend that you upgrade the instance to a later MySQL version at the earliest opportunity.
Effective date
March 01, 2021
Causes
The open source MySQL community no longer provides updates or maintenance for MySQL 5.5.
Impacts
You can purchase RDS instances that run MySQL 5.5. You can also continue using your existing RDS instances that run MySQL 5.5. For example, you can renew these existing RDS instances or upgrade their MySQL versions. However, Alibaba Cloud no longer provides updates or maintenance for the minor engine versions of the RDS instances. Only technical support is provided.
Suggestions
If your RDS instance runs MySQL 5.5, we recommend that you upgrade the instance to MySQL 5.6 or later. This allows you to avoid the known vulnerabilities and issues that may occur in MySQL 5.5. The following two upgrade paths are provided:
Upgrade from MySQL 5.5 to MySQL 5.6. For more information, see Upgrade the major engine version.
Upgrade from MySQL 5.5 to MySQL 5.7 or 8.0. You must create an RDS instance that runs MySQL 5.7 or 8.0. Then, you must migrate the data of your existing RDS instance to the new RDS instance by using Data Transmission Service (DTS). For more information, see Create an ApsaraDB RDS for MySQL instance and Migrate data between ApsaraDB RDS for MySQL instances.
NoteAfter the migration is complete, observe your workloads on the new RDS instance. If your workloads run as normal on the new RDS instance, you can release or unsubscribe from your existing RDS instance. For more information, see Release or unsubscribe from an ApsaraDB RDS for MySQL instance.
