GoDaddy Office 365 to Microsoft Office 365 Tenant-to-Tenant Cutover Email Migration: 7-Days Professional Service

Occasionally, a customer needs migration from GoDaddy Microsoft 365 directly to the Microsoft 365 cloud platform.

Our objective is to provide planning, design, and migration of email services from GoDaddy Microsoft 365 to Microsoft 365.

There will be some email downtime with this migration due to the time required to remove the domain from the Source tenant and add it to the Destination tenant. This is because Microsoft only allows the same domain to exist on one Microsoft 365 tenant at a time. Exchange Online Protection (EOP) can’t route email for the domain during the period when the domain is removed from the Source tenant and added to the Destination tenant, assuming the MX record is pointed at EOP. This results in senders getting a non-delivery report (NDR). Read the "Move domains and settings from one EOP organization to another EOP organization" TechNet article for options to queue email during this time.

If short-term downtime and the possibility of losing some emails are not acceptable for you, please see another service, "Microsoft 365 Tenant-to-Tenant Cutover Email Migration Without Downtime and Bounced Email."
