Availability zone migration guidance overview for Microsoft Azure products and services

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 check the readiness of your application for availability zone support, see Azure availability zone migration baseline.

The table below lists each product that offers migration guidance and/or information.
