Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
Thank you for sharing the validation details.
The error you’re encountering (ResourceMovePolicyValidationFailed with LinkedInvalidPropertyId on Microsoft.Web/certificates) is a known App Service limitation for cross‑subscription moves. If you have free App Service managed certificates, they cannot be moved, and validation fails because the certificate resource has an empty or invalid keyVaultId. Microsoft documents this limitation the recommended workaround.
Supported workaround:
- Remove HTTPS/SSL bindings from the web apps using the affected managed certificates.
- Delete the free App Service managed certificates.
- Retry moving the remaining App Service resources (apps and plans).
- After the move, recreate the managed certificates and rebind them to the custom domains.

- After recreating the managed certificates post‑move, HTTPS bindings should function as expected. If you’re using uploaded/imported PFX certificates instead of free managed certificates, please let me know, as the steps are slightly different
