Cross Forest Migration Exchange 2003 to Exchange 2010 RRS feed

  • Question

  • Hi all,

    Im doing a cross forest migration from windows server 2003 AD and Exchange 2003 to Windows server 2008 R2 AD and Exchange 2010 with the following steps :

    1- Install windows server 2008 AD in anew forest 

    2- Create the trust between the 2 forests prepare the new forest for the users, groups and computers migration

    3- install and configure Exchange server which will be configured as follow:

       - 2 CAS server with windows NLB

       - 2 MBX servers with DAG

       - 2 HUB servers

    i will start the migration by the following :

    - Public Folders and Free/busy Replication

    - Prepare move request

    - migrate global groups

    - migrate users accounts

    - migrate users profiles

    - migrate computers

    - migrate Mailboxes

    after that im confused what to do because i will have both forests coexist for a while till i finish the migration 

    - my question is what do i need to do so users in both forests can send and receive to each other and to out side as well use  (SMTP sharing)  or what ?

    - for the GAL Sync do i need FIM ?

    and what about my member servers in the old environment when can i migrate them?

    - i have SAP server

    - Sharepoint servers

    - File and Print servers

    - CA server

    - FAX server

    - UM server

    how can users in new domain use the servers in old domain and vice versa ?

    If the two forests share the same smtp address space, you could refer to below to the the configurarion in the coexistence period.

    For the question:

    and what about my member servers in the old environment when can i migrate them?

    - i have SAP server

    - Sharepoint servers

    - File and Print servers

    - CA server

    - FAX server

    - UM server
    To UM server, you could follow the the doc to build the server role, and do the needed configuration.
    To other application server, it is better to post the issue on the proper forum to get some help.

  • There's quite a bit of work you have to do and there's more system than just exch.  I'd suggest that maybe you setup a project team and hire consultants for this work or bring in in-house expertise together or consultant the relevant specialists and post in relevant forums.  However, for a project like like this, getting support from forums probably isnt your best option.  You have apps such as SAP, fax etc.

    For the exch side of things, I think you should consider QMM quest - http://www.quest.com/migration-manager-for-exchange/ 

    They also do a product for AD which ties in with exch and this would take care of your AD/exch migrations and keep mailboxes/public flders in synch and access to both envviornments. (Co-exist)  You can use Quest QCS for GAL sync, as well as group, their membershit etc...

    Also have a look at the forums home and see the relevan forums for the products youre using.
