Installing First 2012R2 Domain Controller RRS feed

  • Question

  • My site has two Server 2008 R2 Domain controllers and I have built a replacement pair of Server 2012R2 ready to take over the DC roles.

    I have seen some useful articles showing the upgarde process being completely via the GUI using Server manager add roles etc and then kicking of the dcpromo wizard as per (https://interworks.com/blog/ijahanshahi/2014/01/06/promoting-windows-2012r2-server-domain-controller).

    The last time I went from 2003 to 2008 I had to use some forest prep and adprep commands in an administarive dos box, in order to prepare the AD schema.

    Do I no longer need to perform the ADPREP stages etc?

  • adprep is now an integrated part of domain controller promotion.

    I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting. Then stand up the new 2012, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.

    Also at some point either before or after I'd recommend migrating sysvol replication from older FRS technology to DFSR

  • As Dave has pointed out, this is optional - since the promotion process automatically performs forest schema and domain updates if they are not in place yet.

    Ultimately, it depends on the change control procedures in your organizations. Those more tightly regulated might require separate changes that involve the forest prep and domain prep - others might be more lax, allowing you to carry out all of these changes as part of the domain controller promotion.
