Situation is I have a site using live@edu on a .sch.uk domain and all is fine. The site is to change from a Junior to a Primary over the summer, along with a name change. Now I have the new .org.uk domain name set-up for Office365.
What is the best way to migrate mailboxes from the sch.uk tenancy to the new .org.uk tenancy? Documentation on-line talk about on-premises to cloud migrations, not cloud to cloud.
Thanks in advance.
