Hi Friends,
Let me explain you the scenario. There is this organization which has multiple entities spread aross multiple AD forest. There are two projects that are required to be undertaken
1) Consolidation of all AD forest by creatiing a single forest and single domain. A new forest will be created for this into which all existing forest objects will be migrated or copied.
2) Migration of existing email organizations in the existing forest to the cloud
Can you please suggest what is the exact process i need to follow. The user accounts in all the existing/legacy AD forest will be first migrated to the new AD forest. SID history will be enabled so that users can login to their source AD to access the resources.
Where i am stuck is with migration of existing email environment to exchange online. Can i directly migrate the users in each forest to Office 365/Exchange online ?
Consider forest A as the target forest and forest 1, 2, 3, 4 etc as the existing forest. I am copying the user account associated with say a user Mark (member of Forest 1) to the target forest A as part of AD consolidation. Mark has his mailbox in the onpremise exchange 2010 platform in Forest 1.
How do i move the mailboxes in the Forest 1 to exchange online which is authenticated to Forest A. Should i use third party tools or is this possible with native MS tools? more importantly i am interested in the process that i need to follow.
Also just to reiterate, since there is AD consolidation happening parallely, in the end state, all user accounts will be present in the new AD forest and all legacy forest will be decommissioned.
Can someone please help me here
Regards,
