  • DC Migration

    We have an old Server 2003 machine that's acting as the DC and Exchange box. It's time for this sad little guy to retire.

    We're going to move Exchange to Google Apps, but we need to find a new home for the DC. So we're going to run a VM of Server 2003 R2.. My question is this.. Is this still a valid migration procedure for a DC?

    yea, it's still mostly valid

    However, be really, really careful. You must complete your email migration first.
    If you try and demote the DC role, it'll break exchange because they are installed on the same server

    so i'd do this:

    migrate email, get it done and dusted
    build new server (2008 instead of 2003 maybe ?)
    promo it into the domain
    migrate the FSMO roles
    migrate any other data, roles or functions including dns/dhcp/fileprint

    remove exchange from the old dc
    demote the old DC
    shut it down
    any metadata clean up
    Please do show your appreciation to those who assist you by leaving Rep Point

      In addition, if you are considering bringing up a Virtual Machine for a new DC, I would still recommend that you have at least one DC on physical hardware. In any case, its best practice to have at least two DCs for each domain. This ensures a high level of fault tolerance and availability.
