Upgrading Your Aurora Serverless MySQL Cluster: A Guide from 5.6 to 5.7

Are you stuck trying to upgrade your Aurora Serverless MySQL cluster from version 5.6 to 5.7 using CloudFormation? You're not alone in this dilemma. Many users encounter roadblocks when trying to perform what seems like a straightforward update. In this guide, we'll walk you through the proper process and clarify why your initial attempts may have failed.

The Problem You’re Facing

You may be trying to update the EngineVersion for your Aurora Serverless MySQL cluster from 5.6 to 5.7 in your CloudFormation stack. Although the update seems trivial, it has caused many users to stumble into a critical error:

Many users question why this is treated as an upgrade to a "new major version" when it involves only a minor version change based on standard database versioning. The answer lies in the transition from Aurora Serverless V1 to V2. This shift from one architecture to another complicates the upgrade path and requires a more strategic approach.

A Step-by-Step Solution to Upgrade

Step 1: Create a Snapshot

First, navigate to the AWS Management Console and create a snapshot of your existing Aurora 5.6 serverless cluster. This is crucial for preserving your data and allows you to restore from it if needed.

Step 2: Restore Snapshot to a New Cluster

Next, restore the snapshot into a new Aurora Serverless V2 cluster that supports version 5.7. This step will create a fresh environment that can work with the updated engine version.

Step 3: Import the New Cluster Resource

Once the new cluster is ready, you'll need to import this resource into your existing CloudFormation stack. This process ensures the new cluster is recognized as part of your infrastructure.

Step 4: Update Your Pipeline Template

While doing the above, it’s important to update your deployment pipeline template accordingly. Since you've already imported the cluster into your stack, there is no need for further changes to the template besides reflecting the new cluster resource.

Step 5: Verify Functionality

After deploying the updated stack, verify that everything functions as expected. Check to ensure that all data is intact and accessible in the new 5.7 cluster.

Step 6: Cleanup Old Cluster References

Finally, remove any references to the old V1 (5.6) cluster in your template and CloudFormation stack. This cleanup is important for maintaining an accurate and efficient infrastructure setup.

Conclusion

Upgrading your Aurora Serverless MySQL cluster from 5.6 to 5.7 may not be as straightforward as simply changing the version number in your CloudFormation template. By following this structured approach and understanding the nuances between Aurora Serverless versions, you can achieve a successful upgrade without losing data or causing downtime.
