SCCM CMG - Classic to Virtual scale set

Mohd Atif Husain 120 Reputation points

Dear Team,

We have a situation where CMG is running on Classic deployment method and customer is asking to convert it to Virtual scale set method.

Things to keep in mind is, MS says if your service name is you cannot convert it and here in this case the Service name is not but deployment name is So, question is would that effect the convert procedure? Basically, deployment name and service name are different.

Please suggest a best way to migrate the CMG.

    Based on my understanding, if Service name is not, you can convert it to a virtual machine scale set.

    If your CMG's service name is in the domain, you can't convert it to a virtual machine scale set. For example, you issued a server authentication certificate from your internal PKI with a common name of Since Microsoft owns the domain, you can't create a DNS CNAME to map this service name to the new deployment name in the domain.

    For example:

    The CMG's service name is

    For the deployment name:


    Virtual machine scale set: GraniteFalls.EastUS.CloudApp.Azure.Com
