I used the article below to transfer the FSMO roles from a 2003 to a 2012 server (I only have these 2 servers on the domain). I am getting stuck on Active Directory Schema, Change Active Directory Domain Controller. When selecting the 2012 server and the option to Change "This Domain Controller or AD LDS instance", I get a popup "Active Directory Schema snap-in is not connected to the schema operations master. You will not be able to perform any changes. Schema modifications can only be made on the schema FSMO holder"
When I expand "Active Directory Schema" it lists two folders, Classes and Atributes. AD Users and Computers as well as AD Domains and Trusts list the domain (ie domain.local)
