Answer 1

@T Abhishek We understand you are attempting to move your on-prem web site to an Azure Web App but have received two errors while doing so.

Azure Web Apps does not natively support Windows authentication. You will need to follow the steps listed in this document to manually setup a custom authentication/authorization for your Web App. You can also follow the steps to implement a supported identity provider such as Azure Active Directory.

In regards to location tags, Azure App Service applications are hosted using a preconfigured IIS applicationhost.config file that is built using the selected options for the application.

This check examines the machine to be migrated to see if it depends on configuration options that exist in the IIS applicationhost.config file but are applied at a different level using Location Tags. Any such Location Tag entries must be removed from the applicationhost.config file before the site can be migrated.

Generally, these entries can be moved to either the site's root web.config file, or to a web.config file associated with the specific application to which they apply. Once they've been moved to one of these locations, they can be migrated to Azure App Service with the site content.

Potential Remediation steps:

• Remove the location tags
• For more information see Location Tags.
