Active Directory Migration 2008R2 to 2012 R2

Current Environment

Microsoft Active Directory 2008R2 with Exchange 2010

Requirements for migration

1- New Windows Server 2012 R2 server to be prepared.

2- Join the new Server to the old Dc.

First I will be Installing the new Server windows 2012 R2 which I will migrate all the roles to after preparing it and joining it to the domain as in the following snapshots.

Below I will add the server to the current existing DC.

Here I will leave the default settings but will have to enter the DSRM password as it's mandatory.

to migrate the AD Operations Master roles. The simplest way to move these roles is via PowerShell. On Server 2012 AD PowerShell modules, this can be done from anywhere. Simply run the following command to view you current configuration, and change them:

PS C:\> netdom query FSMO

In order to Migrate all the roles from the DC (Kibtek.local) to the new Server I will use the following powershell cmdlet.

Move-ADDirectoryServerOperationMasterRole -identity "Destination DC's Hostname" -OperationMasterRole 0,1,2,3,4

Once you copy and paste the powershell after you edit the destination host DC name you it will take couple of minutes to migrate all the FSMO roles to the new Server.
