Our internet domain is contoso.com.
Our e-mail addresses are like first_name.last_name@contoso.com
Our Active Directory FQDN (UPN suffix) is local.contoso.com (created due to split-brain DNS problems).
We have been in process of migration from old Active Directory domain contoso.com to newlocal.contoso.com.
This process is going to take another 3-6 months from now.
Our management has just decided to migrate our (non-Exchange) infrastructure into Office365 within 2 months.
We would like to utilize SSO mainly for OneDrive.
How to do it?
I am worried about conflicts with old domain if I change UPN from local.contoso.com tocontoso.com.
