We are planning a migration away from Google Apps for Business handling our email services. The services worked well to get us out of the gate, but now we need to consider scale, both volume and pricing, so we opted to maintain our own email servers.
My question is, is it possible to co-mingle their MX records with our own? My approach would be to add a new MX record for the domain with a priority of 1, and bump all the current Google MX records down in priority, consider the following:
# Current 1 ASPMX.L.GOOGLE.COM 5 ALT1.ASPMX.L.GOOGLE.COM 5 ALT2.ASPMX.L.GOOGLE.COM 10 ASPMX2.GOOGLEMAIL.COM 10 ASPMX3.GOOGLEMAIL.COM # Proposed 1 mail.example.com 5 ASPMX.L.GOOGLE.COM 10 ALT1.ASPMX.L.GOOGLE.COM 10 ALT2.ASPMX.L.GOOGLE.COM 20 ASPMX2.GOOGLEMAIL.COM 20 ASPMX3.GOOGLEMAIL.COM
After we export / import current email accounts I will just remove all google references.
Is this parallel approach possible?
