Moving emails from homestead to google server
We are working to move a client's email server from homestead to google. We are purchasing a new google domain and hosting through google. We are wanting to have everything under google, so (domain, hosting, and email).
My question is: how can we move the emails to Google once we have the new domain and hosting?
The domain would obviously be different than the previous emails the live through homestead. Would they lose all of their old emails?
