How to migrate from Exchange Server 5.5 to Exchange Server 2007 (KB13268) -- NOT REALLY

[ Edited ]

So, RIM posted an article: KB13268 - How to migrate from Microsoft Exchange Server 5.5 to Microsoft Exchange Server 2007

 

Unfortunately Microsoft doesn't support a direct migration from Exchange 5.5 to Exchange 2007.  In fact you cannot install an Exchange 2007 server into your Exchange organization if an Exchange 5.5 server is present.  The Exchange organization needs to be in 2000 native mode before installing your first Exchange 2007 server; which precludes any Exchange 5.5 server from being in your organization.

 

That said, you'd need to install Exchange 2000 or 2003, move mailboes to that server(s), decommision the Exchange 5.5 server, and then you can proceed with setting your Exchange Org to native mode and installing your first Exchange 2007 Server (hopefully that'd be your first CAS, per MS's recommendation).

 

... but what if you don't want to do this ... You could use something from Quest Software  to migrate you directly from 5.5 to 2007; but it certainly won't be free.  And then, can you use the procedure RIM has outlined in the KB article linked above ... well kinda.  All except for step #7.

 

So without further ado, the KB article:

KB13268 - How to migrate from Microsoft Exchange Server 5.5 to Microsoft Exchange Server 2007

 

Procedure

The following permissions for the BlackBerry® Enterprise Server service account must be specified on the new Microsoft Exchange Server through the 2007 Exchange Management Shell:

  • Exchange View Only Administrator role
  • Send As
  • Receive As
  • Administer Information Store

Upgrade the Messaging Application Programming Interface subsystem and allow permissions on the Microsoft Exchange Server 2007

To upgrade the Messaging Application Programming Interface (MAPI) subsystem and allow permissions on the Microsoft Exchange Server 2007, complete the following steps:

  1. Delegate the Exchange View Only Admin role by typing the following command at an Exchange Management Shell prompt, where <BESAdmin> is the name of the BlackBerry Enterprise Server service account:

    Add-exchange administrator "<BESAdmin>" -role ViewOnlyAdmin

  2. Specify the Send As, Receive As, Administer Information Store permissions by typing the following command where <messaging_server_name> is the name of the Microsoft Exchange Server 2007 and <BESAdmin> is the name of the BlackBerry Enterprise Server service account:

    set-mailboxserver "<messaging_server_name>" | add-adpermission -user "<BESAdmin>" -accessrights ExtendedRight -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

    To verify that the permissions have been assigned to the BESAdmin account, type the following command, where <messaging_server_name> is the name of the Microsoft Exchange Server 2007 and <BESAdmin> is the name of the BlackBerry Enterprise Server service account:

    get-mailbox server <messaging_server_name> - add-adpermission -user "<BESAdmin>" -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

  3. Perform a system wide search for the MAPI32.dll and cdo.dll files. Rename any of these files found in the system32 and program files\exchsrvr\bin folder to a .bak file extension.
  4. Install the MAPI and Collaboration Data Objects (CDO) Clients. For instructions, see KB12697.
  5. Restart the BlackBerry Enterprise Server.

    Important: Restarting the BlackBerry Enterprise Server will delay email message delivery to BlackBerry smartphones. For more information, see KB04789.

  6. Assign permissions to the BlackBerry Enterprise Server service account (default name is BESAdmin) on the Microsoft Exchange Server 2007. The following commands are run from the Microsoft Exchange 2007 command line tool.
    1. Delegate the Exchange View Only Admin Role with the following command, where BESAdmin is the name of the BlackBerry Enterprise Server service account:

      add-exchangeadministrator BESAdmin -role ViewOnlyAdmin

    2. Set the Send As, Receive As, Administer Information Store permissions by typing the following command, where <Exchange2007> is the name of the Microsoft Exchange Server 2007 and <BESAdmin> is the name of the BlackBerry Enterprise Server service account:

      set-mailboxserver <Exchange2007> | add-adpermission -user <BESAdmin> -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

  7. Move the Microsoft Exchange 5.5 mailboxes from the Microsoft Exchange Server 2007 using the built-in mailbox move utility.
  8. Run the handheldcleanup.exe utility with the -u switch. For instructions, see KB00140.
  9. Resolve the MAPI profile for the BlackBerry Enterprise Server service account mailbox on the Microsoft Exchange Server 2007 by going to Start > Programs > BlackBerry Enterprise Server > Edit the MAPI.


Additional Info

BlackBerry Enterprise Server software version 4.1.3 and later are supported for Microsoft Exchange Server 2007.

During the Microsoft Exchange Server 2007 installation, choose the option to allow Microsoft® Outlook® 2003 and earlier versions when prompted.
