Hello @KE1980 ,
AFAIK, it is not possible to rename the Azure Front Door from its initial name to another.
Please refer : https://learn.microsoft.com/en-us/powershell/module/az.frontdoor/set-azfrontdoor?view=azps-5.0.0
"-Name" parameter in "Set-Azfrontdoor" powershell cmdlet is just to provide the name of the existing Front Door which you want to update. Accept pipeline input for this parameter is False and cannot be changed.
Hope this helps!
Kindly let us know if the above helps or you need further assistance on this issue.
