It is super easy to transfer your email data, and even your existing domain registration(s), to us. To prevent any downtime in email function, the correct order of operations is: create a new account, transfer a copy of your data to the new server, update the DNS of any domain(s) to point to the new server, wait 24 hours and verify everything loads from the new server, cancel old hosting account, initiate domain registration transfer, verify the domain registration transfer completed successfully. This sounds daunting at first, but taken one step at a time it's a very easy and a logical sequence.
