We're about to remove the Central Admin Site from our ConfigMgr 2103 environment. We currently have a single CMG deployed with cloud service classic.
I had been informed here that it should be possible to remove the existing CMG then reinstall at the Primary Site Server using the same CName and certificate and internet clients would just reconnect to the new CMG without us having a requirement for them to be back on the intranet at some point.
I've noticed that the cloud service classic has just been deprecated this month however. What I'd like to know is if this means it won't be possible to reinstall the CMG at the Primary Site via this method. Does anybody know if the deprecation notice now means this isn't possible?
