Unable to reinstall SCVMM 2012 R2 during database migration - access denied to VMMDKM container

Question

I'm trying to migrate my SCVMM 2012 R2 DB to a new SQL 2012 server. As per TechNet article http://technet.microsoft.com/en-us/library/dn469626.aspx,
I uninstalled VMM, which went without a problem. During the reinstall, setup fails with "Unable to create or access the Active Directory container CN=VMMDKM,CN=System,DC=feroscare,DC=local. Access is denied. Specify the distinguished name
for the container and verify that you have GenericRead|CreateChild|WriteProperty rights on the container." - as is shown in the setup log below.
I'm trying to use the same account as the service account and to connect to the database. I'm logged into the VMM server as that user account (and running setup as that account). I have verified that the account has full control over the VMMDKM container
and all descendant objects. I've also added these permissions for the VMM server's computer account, although I'm not sure that's necessary.
VMM server is running Win 2012 R2, SQL server is 2012 running on Win 2012 R2. Domain controller is running 2008 R2 with AD at the 2003 functional level.
Please can anyone please advise what to do next to troubleshoot this?
What seem to be the relevant lines from the VMM setup log:
"12:33:04:Error:SetupDKM method threw. See inner exceptions, Exception Type: System.DirectoryServices.DirectoryServicesCOMException, Exception Message: A constraint violation occurred.

Thanks in advance!
