I'm migrating multiple websites from windows server 2012 to windows server 2022 using web deploy.

When I try to view the site in a web browser, some of them have problems, I view the site and get "500 Internal Server Error". How to fix this error?

    First of all, you may need to check whether the necessary feature has been installed, such as Common HTTP Features, Application Development, Management Tools etc.

    Secondly, considering it is migrated from windows 2012, you could try to set application pool to classic mode and enable 32-bit applications in application pool advanced setting.

    500 internal server error is generic error.

    If you migrate site from - to, you check that target server has all IIS features of source IIS Server.

    You must check .net on target server, and you must re-create application pool of migrate site because identity pool could be wrong.
