Hi,

We plan to migrate the on-prem AD to Azure, but the problem is that our on-prem AD has a different domain than our O365.

On-Prem domain - abc-all.com

O365/Azure domain - abc.com

I need your expertise to resolve this issue.

Thanks.

Achyut G.

    Hello Achyut Gosavi,

    Thanks for your question.

    If this is the case, I will recommend you consider using a non-routable domain locally as a domain suffix

    See: https://learn.microsoft.com/en-us/microsoft-365/enterprise/prepare-a-non-routable-domain-for-directory-synchronization?view=o365-worldwide&source=recommendations

    Before doing the above please remember to go through the steps for Directory sync preparation here:

    https://learn.microsoft.com/en-us/microsoft-365/enterprise/prepare-for-directory-synchronization?view=o365-worldwide

    You can test this by syncing some test users via OU filtering.
