SBS 2003 to SBS2011 Migration: Installation issues - Exchange Server 2010 cannot be installed

    Question

  • Hello,

    I'm currently migrating from Windows Small Business Server 2008 to Windows Small Business Server 2011.

    After Windows Small Business Server 2011 was installed I reviewed the installation issues which are as follows:

    Exchange Server 2010 cannot be installed.

    I attempted to manually install Exchange Server 2010 from the SBS 2011 media which came back with the following errors:

    Summary: 6 item(s). 3 succeeded, 3 failed.

    Any help would be greatly appreciated. Thank you.

    *NOTE: The SBS2008 server was migrated from SBS2003 (onto completely new hard ware). the source server (SBS 2008) has Exchange 2007 SP3 installed.

  • Just an update.

    I've done some digging and found on the SBS 2008 server Exchange Server 2007 is version 08.03.0298.001 however the Hub Transport, Client Access, and, Mailbox roles are version 8.1 (build 240.6).

    I've also found that when I checked the ExchangeSetup.log file on the SBS 2011 server I can find the following errors:

    [REQUIRED] Coexistence between Exchange Server 2010 and Exchange Server versions older than Exchange Server 2007 SP2 in the same Active Directory Site is not supported.

    [RECOMENDED] Installing Exchange Server on a domain controller will elevate the privileges for Exchange Trusted Subsystem to domain administrators.

    This may be why the installation of Exchange 2010 is failing on the SBS 2011 server. Would the resolution be to simply attempt to re-install Exchange Server 2007 SP3 onto the SBS 2008 server?

  • I hope you have good backups for the SBS 2008.  A failed migration is very difficult to recover as the source was not properly prepped so the destination is not going to be happy.  I suggest you restore the SBS 2008, get it properly prepped, run all the pre-migration tools, and begin again.
