Domain Controller Migration from 2008 R2 to 2016 Standard

    Question

  • Hi,

    I am about to migrate our Domain Controllers from 2008 R2 to 2016 Standard.  Can someone please validate the following steps for domain controllers migration from 2008 R2 to 2016 standard?--I just need a second eye:

    Scenario:

    • DC1 and DC2 are two physical DCs running Win2008 R2
    • DC1 has all master roles--schema master, domain naming master, PDC, RID pool manger, and infrastructure master
    • DNS role (AD integrated) is on both DCs
    • All member servers are running Windows 2012
    • All member workstations are running Windows 10.

    Summary of Steps to migrate DC2 to 2016:

    1. Run general diagnostics on DC2 (dcdiag, netdiag, repadmin /showrepl, etc.)
    2. Backup DC2 (e.g.: wbadmin start backup -backupTarget:F: -allCritical -systemState)
    3. Decomission DC2 (dcpromo)
    4. On DC2, boot from Windows 2016 flash drive and format DC2 and install the OS
    5. Re-join the domain as DC2
    6. Add server roles--ADDS, Group Policy Management, DNS
    7. Add DC2 as a domain controller to existing domain and make sure Global Catalog is checked.
    8. Configure database (NTDS), Log, and SYSVOL locations
    9. Configure DNS
    10. Reboot as needed

    Summary of Steps to migrate DC1 to 2016:

    1. Migrate all FSMO roles from DC1 to DC2
    2. Follow steps 1-9 above, but as DC1.
    3. Migrate all FSMO roles back from DC2 to DC1

    Does this sound reasonably ok?

    Thank you,

    -sul.

  • Should work. After building the new 2016 servers first step should be to patch it fully.
