Before you begin the upgrade, we recommend that as a best practice you back up the user database on the Evaluation Edition of your Enterprise pool or Standard Edition server by using Dbimpexp.exe. By default, Dbimpexp.exe is installed on the server computer at <drive>: \Program Files\Common Files\Microsoft Office Communications Server 2007 R2\Support. For details about using Dbimpexp, see the dbimpexp-readme document in the same folder.

To back up the user database

  1. Log on to the Office Communications Server 2007 R2 Standard Edition Server or the Enterprise pool Back-End Database as a member of the Administrators group.

  2. At a command prompt, set the default folder to <drive>: \Program Files\Common Files\Microsoft Office Communications Server 2007 R2\Support folder. At the command prompt, type one of the following, substituting the path and name of your user data file and for an Enterprisse pool, the name of your SQL Server host:

    • On a Standard Edition Server

      Copy Code
      dbimpexp.exe /hrxmlfile:"c:\SavedUserData.xml"
      
    • For an Enterprise pool

      Copy Code
      dbimpexp.exe /hrxmlfile:"c:\SavedUserData.xml" /sqlserver:<sql
      server host name>
      

    You can place the XML file anywhere, as long as you specify the full path.
