I've got a gmail domain setup for mycompany.com with years price of back emails, labels, and configurations, a couple of dozen customers, in addition to various user groups. However, lately, because of some technical restrictions, i have been requested to maneuver gmail to dev.mycompany.com to permit the main domain (mycompany.com) to become running microsoft exchange rather. I attempted establishing an alias for dev.mycompany.com however the user groups aren't effective. I can not find any information about how emigrate a gmail domain to another domain or perhaps a subdomain, everything i've found is all about moving from whatever i had been running before gmail to gmail. I'd rather not begin with scratch, since we've years price of email configurations and labels that might be lost, even when we did import the mail itself. Does anybody understand how to correctly do that?

Thanks.
