Windows Server 2003 domain-controlled upgrade to Server R2

Windows Server 2003 domain-controlled upgrade to Server R2

Summarize:

Knot
To summarize, if we want to start from scratch, we need to upgrade the WINDOWS2003 domain control to the Windows2012 domain name. Note: Before upgrading the schema, you must first debug the cmd---dcdiag (Microsoft Many upgrade projects are also the same). Wait for the wrong row, then arrange the time to do the upgrade. If it's not wrong, there may be a lot of problems that were previously small, and upgrading the architecture became a big problem. After lifting the * * * for the additional domain controller, transfer the FSMO five role commands: Use Transfer infrastructure master transport infrastructure host to the domain controller using Transfer naming master to transfer the named host to the domain controller Using the Transfer PDC to transfer the PDC to a * * * domain controller

Use Transfer RID master to transfer the RID master to a domain controller using Transfer schema master to transfer the schema master to the domain controller

1. Add an additional windows2008r2, a WindowsServer2012, and join the Windows2003 domain. 2. Extend the Windows2003 architecture to 2008R2 3. Promote the WINDOWS2008R2 to a domain controller. 4. Promote the Windows2012 to a domain controller. What if you need to raise the functional level of the domain and forest to 2012 more operations? 1. Transfer the primary domain control of the five roles to the 2008R2 (may go directly to 2012, not tried, do not know if it is feasible), downgrade 2003. 2. Raise the functional level of the domain and forest to 2008R2, transfer five roles to 2012, demote 2008R2 3. Raise the functional level of the domain and forest to 2012. ============================ we can see, the whole migration process is very long, which must take windows2008r2 as a pedal, although in 55 steps to find a big surprise, but never seriously, how to do and how to do, successfully completed the upgrade. In a production environment, if there are 10 domain controls or more, it is best to be cautious about raising the functional level, and if you just want to use WindowsServer2012 's functionality, add an additional 08R2 domain control. If you need to upgrade all, then it is best to do a good plan, after all, functional level of upgrading, the need to downgrade all the old system, the workload should be considered in advance.
