ADMT 3.2 target and source domain functional level requirement

    Question

  • Hello,

    I am planning on doing an AD Forest migration to a new Forest. I understand that in the target forest, we need to have at-least one 2008 R2 domain controller. We cannot have the target FFL and DFL at 2012.

    But I am not clear on what are requirements in the source forest.

    What if the source forest has already been upgraded to 2012 FFL and DFL and client has removed all the 2008 & 2008 R2 domain controllers?

    Can someone please advise?

    Thanks in advance.

  • Hello,

    For ADMT 3.2 minimum functional level is Windows Server 2003.

    If you need migration from  2003 to  2012, at this time MS has not ADMT for Windows Server 2012.
    You can downgrade your forest and Domain functional level to Windows Server 2008 R2, add a additional Domain Controller 2008 R2 and use ADMT 3.2 for migration. After migration is completed, you can demote Domain Controller 2008 R2 and raise again FFL & DFT to Windows Server 2012.
