I am facing an issue with my Azure Front Door on the Standard plan, which was migrated from the Classic plan. This Front Door uses a "migrated domain", which is the default domain generated by Microsoft (xxxx.azurefd), and all my clients use this domain to communicate with my Front Door.

Now, I need to associate a new route (with a new URL) to this domain, but when I try to do so, I get the following error: "Migrated domain can only be added to the original route."

I would like to know how I can work around this limitation and associate a new route to my migrated domain.

Is there any alternative configuration or procedure I can follow to allow this? I need to keep the same domain that my clients are using and add new routes as needed.

Thank you in advance for your help!

You can then create new routes associated with this custom domain. Update your DNS with a CNAME record pointing your custom domain to your xxxx.azurefd address. Optionally, use a rule set to redirect traffic from the xxxx.azurefd domain to your custom domain. This gives you full control and avoids the limitations of the migrated domain.

Less ideal workarounds exist (like URL rewriting), but they are complex and limited. Creating a new Front Door profile is not recommended as it changes the domain your clients use.
