In November of 2022, we launched the zero downtime migration tool in public preview and received a lot of feedback and interest from our users. We truly appreciate your participation and input very much. We’re happy to announce the migration capability is now generally available with improvements in reliability and stability.
We’re also happy to announce the general availability of both Managed Identity for Azure Front Door retrieval of your own certificate from Azure Key Vault and upgrade your tier from standard to premium with this release. To migrate from classic to standard/premium, you need to enable Managed Identity as a required step if you’re using your own certification.

Notable changes post migration
Migration pricing assessment
Azure Front Door Standard and Premium and Azure Front Door Classic have different pricing models. When migrating from Azure Front Door (classic) to Standard or Premium, we recommend you do a cost analysis to understand the pricing differences between the tiers. Unlike the Classic SKU, each Azure Front Door Standard and Premium profile incurs an hourly base fee. The rate you're charged depends on the Azure Front Door SKU that you deploy. In most cases, Azure Front Door Standard and Premium have a lower total cost of ownership than Azure Front Door (classic). If you have a request-heavy workload, it's recommended to estimate the impact of the request meters of the new tiers. If you have multiple instances of Azure Front Door, it's recommended to estimate the impact of the base fee of the new tiers. You should migrate only the workloads you need and delete any Azure Front Door (classic) unused resources. You can find more information on Pricing - Front Door | Microsoft Azure and Azure Front Door Tiers Pricing Comparison.
Start migration now!
Azure Front Door Classic will remain operational for the time-being, but it is recommended for customers to migrate to the Azure Front Door Standard and Premium because these SKUs offer better reporting and diagnostic capabilities, enhanced rules engine with server variables, better Web Application Firewall (latest DRS rule set, Bot protection, Web Application Firewall Notebook using Sentinel for security investigation and monitoring, Microsoft Sentinel Analytics) and security capabilities (Private Link connectivity to your origin, subdomain takeover prevention), and many new upcoming features that you can benefit from. We encourage you to begin planning migration in the near future. One of the new upcoming features that is already in private preview is WebSocket. We will also share previews for some other highly requested features soon. If you are interested in trying out WebSocket or want to learn more about the upcoming features, please reach out to afdprivatepreview@microsoft.com or your sales representatives.
