Hi guys,
How would I go about checking out how long it would take for the DNS cutover time to finish.
I haven't done a O365 tenant to tenant migration before and I will be shortly, To my understand if you are keeping the same doman name then its just a matter of logging into the dns server / cpanel and changing the MX record but I don't know how long the cutover time will take? how would I go about finding this out / checking it?
