AD Trust between two domains with same NETBIOS name

Annas Umair 1 Reputation point

Hi All,

We have Domain A and Domain B with same NETBIOS name. We were looking to migrate users and machines from Domain B to Domain A and then eventually decommission Domain B. Can we create a trust between the two domains? If not what options do we have?

Domain A is on 2016 DFL and FFL
Domain B is on 2012R2 DFL and FFL.

Thanks for the help in advance.

    Based on my research, you must resolve the conflict for the Netbios Name.
    So we need to rename one of the domain names.

    For how to create a trust between forests, you can refer to :

    It is also the suggested method to migrate users and machines through the ADMT tool.
