Your network contains an Active Directory domain named contoso.com.
The domain contains a server named Server1 that runs Windows Server 2012 R2. Server1 has the IP Address Management (IPAM) Server feature installed.
IPAM is configured currently for Group Policy- based provisioning.
You need to change the IPAM provisioning method on Server1.
What should you do?
A.
Run the ipamgc.exe command.
B.
Run the Set-IPAMConfiguration cmdlet.
C.
Reinstall the IP Address Management (IPAM) Server feature.
D.
Delete IPAM Group Policy objects (GPOs) from the domain.
Explanation:
You cannot change the provisioning method after completing the initial setup.
It can only be changed from Automatic to Manual (GPO). Not GPO to automatic.
and from auto -> GPO .. is only possible if data is on SQL
According to MS documentation, the provisioning type can not be changed after installation (regardless of DB type).
Provisioning can only be specified during installation of IPAM. It is possible to fully configure IPAM as though it has been installed with GPO provisioning, but it is a very long and complicated process. Microsoft stresses the use of GPO provisioning in all their documentation and guidelines:
