We're updating from VAMT 2 to VAMT 3 for KMS licensing of our Windows 7 installations. We have a new server configured with VAMT 3 and have changed the DNS entries to point KMS licensing to the new host. Do we need to manually activate machines in order to get the new KMS server running (you typically need a minimum number of requests before the server will begin auto-activation) or will those requests happen by themselves as the machines check for renewal?
