# Uninstall the solution
<a name="uninstall-the-solution"></a>

**Note**  
Infrastructure resources that maintain data (for example, S3 buckets, RDS instances, DynamoDB tables) are configured with a `RETAIN` removal policy. Running `mdaa destroy` will not remove these resources, so your data is preserved.  
However, some non-retained resources (for example, Security Groups) may depend on retained resources like RDS or OpenSearch instances. In these cases, the destroy can fail or take a long time to complete. To avoid this, delete the retained resources first before running `mdaa destroy`.

Follow these steps to uninstall the solution:

1. Run `mdaa destroy` using the same configuration file (`mdaa.yaml`) that was used for deployment. This tears down all remaining MDAA-managed stacks in the correct dependency order.

   ```
   mdaa destroy -c ./mdaa.yaml
   ```

1. Delete any retained data resources (for example, S3 buckets, RDS instances, DynamoDB tables, OpenSearch domains) that are no longer needed. These resources will have the organization name as a prefix.
