Changing computer domains when using Azure AD Sync
- 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.
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?
Of course. So company B and company A were completely separate. Both have their own AD domains and both had their own Office 365 tenants with all their domains and users. Both were using Azure AD sync to sync users for passwords, etc. When Company A purchased Company B, we used Bit Titan Migration to copy all the users from B into A's 365 tenant. Now company B's 365 tenant is no longer used and the licenses were removed. All the domains, mailboxes etc now exist in Company A's tenant. There is a two way trust between the two domains so when the sync runs from the company A server it can see all the users in the B domain and still sync the passwords.
Administration now wants to take all the computers that are on the B domain and move them to the A domain in the local AD. So all the mailboxes live in one 365 tenant yet are being synced from two separate domains.

That is what i was assuming but wanted to ask. I will check out the groups as you recommended but thank you fro the assistance with this. I plan do so some testing but wanted to have an idea going into it as to what the steps may be.
