Azure PowerShell - Request to a downlevel service failed

Azure PowerShell - Request to a downlevel service failed

Issue:

·       Sometime when we run the PowerShell command, we get following error message,

o   Request to a downlevel service failed

·       Example: Switch-AzureWebsiteSlot

Solution:

The reason for error message “Request to a downlevel service failed” is Deprecating Service Management APIs.

Issue was happening because your CmdLets are using the Service Management API which is deprecated for Azure App Service.

You can get more information on below URLs,

To resolve this, You should implement the ARM equivalent.

Your command should have “RM” e.g. Switch-AzureRmWebAppSlot instead of

Switch-AzureWebsiteSlot

I hope this helps.
