Upgrade an MLFlow Tracking Server

### Product Category

Experiments

### Question

Previously only version v2.13.2 of mlflow tracking server was available. Last week v2.16.2 became available. How do I upgrade my older tracking server without losing all my experiment data? There doesn't seem to be any documentation about it.

### Other Details

As a note, I set up the mlflow instance using cloudformation, not through the UI. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-sagemaker-mlflowtrackingserver.html

I figured setting the weekly maintenance window would have auto upgraded my mlflow server during that window?

Start with the linked AWS CloudFormation SageMaker MLflow tracking server resource documentation and the issue's question about upgrading from v2.13.2 to v2.16.2. Determine the supported upgrade path, whether experiment data is preserved, and whether the maintenance window performs upgrades; document the confirmed process and its prerequisites.
