-## PostgreSQL 11 support in Azure Database for PostgreSQL single server and Azure Database for PostgreSQL flexible server
-
-Azure is extending support for PostgreSQL 11 in Azure Database for PostgreSQL single server and Azure Database for PostgreSQL flexible server by one more year until **November 9, 2024**.
-
-- You will be able to create and use your PostgreSQL 11 servers until November 9, 2024 without any restrictions. This extended support is provided to help you with more time to plan and [migrate to Azure Database for PostgreSQL flexible server](../migrate/concepts-single-to-flexible.md) for higher PostgreSQL versions.
-- Until November 9, 2023, Azure will continue to update your PostgreSQL 11 server with PostgreSQL community provided minor versions.
-- Between November 9, 2023 and November 9, 2024, you can continue to use your PostgreSQL 11 servers and create new Azure Database for PostgreSQL flexible server instances without any restrictions. However, other retired PostgreSQL engine [restrictions](#retired-postgresql-engine-versions-not-supported-in-azure-database-for-postgresql-flexible-server) apply.
-- Beyond Nov 9 2024, all retired PostgreSQL engine [restrictions](#retired-postgresql-engine-versions-not-supported-in-azure-database-for-postgresql-flexible-server) apply.

+## PostgreSQL 11 support
+
+Azure is extending its support for PostgreSQL 11 within both the Azure Database for PostgreSQL Single Server and Azure Database for PostgreSQL Flexible Server platforms. This extended support timeline is designed to provide additional time for users to plan and [migrate to Azure Database for PostgreSQL flexible server](../migrate/concepts-single-to-flexible.md) for higher PostgreSQL versions.
+
+### Single Server support:
+- Until March 28, 2025, users can continue to create and utilize PostgreSQL 11 servers on the Azure Database for PostgreSQL Single Server, with the exception of creation through the Azure portal. It's important to note that other [restrictions](#retired-postgresql-engine-versions-not-supported-in-azure-database-for-postgresql-flexible-server) associated with retired PostgreSQL engines still apply.
+- Azure will offer updates incorporating minor versions provided by the PostgreSQL community for PostgreSQL 11 servers until November 9, 2023.
+- After March 28, 2025, all PostgreSQL 11 servers on Single Server will be subject to the restrictions that are in place for retired PostgreSQL engines.
+
+### Flexible Server support
+- Users can create and operate PostgreSQL 11 servers on Azure Database for PostgreSQL Flexible Server until November 9, 2025. 
+- Similar to the Single Server, updates with PostgreSQL community provided minor versions will be available for PostgreSQL 11 servers until November 9, 2023.
+- From November 9, 2023, to November 9, 2025, while users can continue using and creating new instances of PostgreSQL 11 on the Flexible Server, they will be subject to the [restrictions](#retired-postgresql-engine-versions-not-supported-in-azure-database-for-postgresql-flexible-server) of other retired PostgreSQL engines.
+- Post November 9, 2025, PostgreSQL 11 servers on Flexible Server will fully adhere to the restrictions applicable to retired PostgreSQL engines.
+
+This extension of support is part of Azure's commitment to providing a seamless migration path and ensuring continued functionality for users relying on PostgreSQL 11.

 ## Retired PostgreSQL engine versions not supported in Azure Database for PostgreSQL flexible server
 
 You might continue to run the retired version in Azure Database for PostgreSQL flexible server. However, note the following restrictions after the retirement date for each PostgreSQL database version:
