General availability: Azure Front Door Migration from classic to standard/premium

In March 2022, we [announced the general availability](https://azure.microsoft.com/en-us/blog/introducing-the-new-azure-front-door-reimagined-for-modern-apps-and-content/) of two new Azure Front Door tiers. Azure Front Door Standard and Premium are our native, modern cloud content delivery network (CDN) catering to both dynamic and static content delivery acceleration with built-in turnkey security and a simple and predictable pricing model. The migration capability enables you to perform a zero-downtime migration from Azure Front Door (classic) to Azure Front Door Standard or Premium in just three simple steps or five simple steps if your Azure Front Door (classic) instance has custom domains with your own certificates. The migration will take a few minutes to complete depending on the complexity of your Azure Front Door (classic) instance, such as number of domains, backend pools, routes, and other configurations.
