Windows Server 2003 Domain Control Upgrade to Server 2012 R2

Summary:

Knot:

To sum up, if we want to start from scratch, what do we need to upgrade the domain control of Windows2003 to the domain name of Windows2012? Note: cmd---dcdiag must be typeset before upgrading the architecture (this is also true of many Microsoft upgrade projects). After the wrong arrangement is done, arrange time to upgrade. If you do not make mistakes, there may be many problems that used to be small problems, but after upgrading the architecture, they become big problems. After upgrading *** to additional domain controller, transfer FSMO five role commands: Transfer infrastructure master to *** domain controller Transfer naming master to *** domain controller Transfer PDC to *** domain controller

Transfer RID master to *** domain controller using Transfer schema master Transfer schema master to *** domain controller

1. Add an additional Windows2008R2 and Windows Server 2012 to the Windows2003 domain. 2. Extend Windows2003 architecture to 2008R2 3. Promote Windows2008R2 to Domain Controller. 4. Promote Windows2012 to Domain Controller. If you need to upgrade the domain and forest functional level to 2012, you should need more actions. What are they? 1. Transfer five roles of master domain control to 2008R2 (maybe go directly to 2012, not tried, not sure if it is feasible), downgrade 2003. 2. Upgrade domain and forest functional levels to 2008R2, transfer five roles to 2012, demote 2008R2 3. Upgrade domain and forest feature levels to 2012. ============================ In a production environment, if there are 10 domain controllers or more, then it is best to be cautious about upgrading the functional level. If you just want to use the functions of Windows Server 2012, then add an additional 08R2 domain controller. If you need to upgrade all of them, then it's best to make a perfect plan. After all, the upgrade of the function level needs to downgrade all the old systems, and the workload should be considered in advance.
