Hello everyone, I am in the middle of testing a 2003 to 2012 domain controller migration. I have cloned our 2 current 2003 DC's and spun up 2 additional 2012 DCs, all of this in an isolated virtual environment. I have transferred all roles to the 2012 DC's, everything went fine. I am now at the point of demoting the 2003 DC's, during the dcpromo process I am prompted with "This domain controller holds the last replica of the following application directory partitions: DC=TAPI3Directory,DC=xxx,DC=local. I understand that TAPI3 is used for telephony that relies on AD. I cannot get a clear answer (recent turnover) whether we actually need this. My question is, how can I copy/replicate/move or re-create this Application Directory Partition on a Server 2012 DC? Everything I research leads to tapicfg but this is not a valid command in server 2012. If there is a way to do this can someone please explain?
Thanks for your time.
Damien
