Hi,

I have Windows server 2003 SP2 Active Directory.

Can you please let me know the right procedure to migrate to AD 2012 R2 SP1, on a new server.

Also how will I transfer the DNS and DHCP (which are currently installed on 2003 DC) to the new 2012 DC?

Thanks.

Yes, we have exchange 2007 SP1 running on a separate server. I will upgrade it to SP3 RU13 and then it is compatible with AD 2012 R2 SP1. If it is not correct please let me know.

Thanks,

Exchange 2007 has no updates that allow it to properly work with 2012 R2 domain controllers. So for now, you cannot safely do what you want.

As an aside, there is no SP1 for 2012 R2.

If you are referring to going to a Server 2012 R2 functional level then Cliff is correct, It is not supported. If you are wanting to just update your Domain Controllers to Server 2012 R2 and keep your functional level below Server 2012 on your domain or forest then it is possible. Please clarify
