-# Availability zone migration guidance overview for Microsoft Azure products and services
+# Availability zone migration guidance overview
 
-Azure services that support availability zones, including zonal and zone-redundant offerings, are continually expanding.  For that reason, resources that don't currently have availability zone support, may have an opportunity to gain that support. The Migration Guides section offers a collection of guides for each service that requires certain procedures in order to move a resource from non-availability zone support to availability support. You'll find information on prerequisites for migration, download requirements, important migration considerations and recommendations.
+To improve the reliability of your solution, it's a good practice to enable availability zone support on your Azure resources. Most services require that you follow certain procedures in order to enable availability zone support on an existing resource. In the list below, you'll find guides to support availability zones on many Azure services. These guides provide detailed information such as prerequisites for migration, expected downtime, important migration considerations, and recommendations.
 
-The table below lists each product that offers migration guidance and/or information.
