Changing computer domains when using Azure AD Sync
I have a client that was purchased by another company. (Company A purchased Company B). Both Company A and Company B on their own were using Office 365 and Azure AD Sync. All users and mailboxes from...
- Considering the only thing that really matters to azureAD sync is the users, there should be no affect since you have the domains in the now same tenant. The biggest thing would be if you have any kind of security groups with devices in them you'll need to look that over, but from a 365 perspective, it shouldn't matter, the device is just moving over.
I guess the question is, the users from Company B being moved, how are they in Company A? Are they cloud only users or do they exist in Company A's domain?
As of now Company B is all in their own AD domain and Company A is all in their own AD domain. Part of this process and what the question is, is after users from Company B are moved to Company A's domain, what happens when Azure sync runs? Since they were being synced from Company B's domain but are now in Company A's domain will they sync correctly and will Office 365 know that it is the same users?
