    Migrating from SBS 2003 to Server 2008 and Exchange 2007

    I need to migrate an existing SBS 2003 system to a new Windows Server 2008
    box, which will also be running Exchange 2007. As I will not be retaining
    any of the 2003 software I would prefer to avoid the expense of the
    Transition Pack for SBS. I have read some conflicting / confusing advice on
    the best route for making this transition - here is the process as I
    understand it but I would appreciate any comments, particularly if I have
    missed something obvious.

    My plan is:
    * Add the new 2008 server as a member server in the existing SBS 2003 domain.
    * Run adprep on the SBS to update the AD schema.
    * Promote the 2008 box to being an additional Domain Controller. I believe
    that I have to do this before installing Exchange otherwise the promotion to
    DC breaks Exchange.
    * Install Exchange 2007 on the Server 2008 box and add to the domain.
    * Move data to the new server.
    * Transition mailboxes to the new server.
    * Move group policies etc. to 2008 server.
    * Transition FSMO roles from SBS 2003 to 2008 server.
    * Remove SBS 2003 server from domain.

    Does this plan look anything like sensible, or have I missed anything
    important? Any help or comments much appreciated.

    Thanks,
    Paul

    Hello Paul,

    It is and was not recommended to install exchange on Domain controllers,
    especially Exchange 2007 should not run on DC's. Also you can not just move/transfer
    roles from a SBS server to another domain controller, as SBS server MUST
    have the 5 FSMO roles, that is by design. Also make sure that you have NO
    single lable domain name like DOMAIN, you have the need for DOMAIN.LOCAL
    when installing Exchange 2007.

    I strongly recommend to post this to:
    microsoft.public.windows.server.sbs

    Best regards

    Re: Migrating from SBS 2003 to Server 2008 and Exchange 2007

    Thanks for the reply Meinolf. I am slightly confused by the Exchange on a DC
    issue as I thought that this was a configuration that is supported by
    Microsoft, and presumably SBS 2008 is exactly that. What are the drawbacks?

    In terms of FSMO roles, I understand that an SBS machine will not run
    without these roles - in fact I have read is that SBS 2003 will reboot every
    hour if it finds itself without those roles. For that reason I was planning
    to make the transfer of those roles the very final step before removing the
    SBS machine completely from the domain and then decommissioning it totally.
    Will that work?

    Many thanks,
    Paul

    Hello Paul,

    In your first posting you mentioned server 2008 and not SBS 2008. SBS versions
    of windows are alway different then the other server versions.

    Again, especially changing from sbs 2003 to sbs 2008 use the NG from my previous
    posting, there you find the experts.

    Best regards

    Re: Migrating from SBS 2003 to Server 2008 and Exchange 2007

    Apologies, my last post was not clear. I am upgrading from SBS 2003 to
    Windows Server Standard 2008 and Exchange 2007, not to SBS 2008. What I was
    trying to ask was why it is such a bad idea to run Exchange 2007 on the DC.

    I have also cross-posted to the SBS group.

    Thanks,
    Paul
