 #### Amazon RDS Blue/Green Deployments
 
-**Important: Service Dependency**
-
-Support for Blue/Green deployments using the AWS Advanced JDBC Wrapper requires specific metadata tables that are **not available in the current RDS and Aurora service**. Please contact your AWS account team for metadata release timelines.
-
-**Limitations:**
-
 - **Post-switchover failures:** After a Blue/Green switchover, the wrapper may not properly detect the new cluster topology, leading to failed failover attempts.
 - **Metadata inconsistencies:** Discrepancies between topology metadata and actual available endpoints prevent reliable operation.
 - **Version-specific issues:** Requirements vary between Aurora MySQL and Aurora PostgreSQL due to different internal systems.
 
-**If You Must Use Blue/Green (Not Recommended for Production):**
-
-1. Enable the `enableGreenNodeReplacement` configuration parameter.
-2. Thoroughly test in non-production environments.
-
 **Recommendation:**
 
 We advise waiting for the RDS service update before enabling the Blue/Green Deployments plugin. If the metadata table does not exist, your application will continue to work; however, errors will be logged stating that relevant Blue/Green metadata cannot be found.

 The AWS JDBC Driver leverages the Blue/Green Deployment approach by intelligently managing traffic distribution between blue and green nodes, minimizing the impact of stale DNS data and connectivity disruptions on user applications.

The metadata will be accessible provided the green deployment satisfies the minimum version compatibility requirements. This constraint **does not** apply to RDS MySQL.
