    Yes, a migration from both Exchange 2003 and Exchange 2007 to Exchange 2010 will be supported.  As shown in the article Transitioning to Exchange 2010, you can see that Excahnge 2003 is supported.

    "You can only transition to Exchange 2010 from the following existing messaging systems:
    • Exchange 2007 messaging system
    • Combined Exchange 2003 and Exchange 2007 messaging system

    This means that if you are upgrading from an Exchange 2003 or Exchange 2007 organization, you can choose to either transition the organization, or migrate to a new organization. In most cases, you will want to retain the Exchange data from the existing organization, and so you should choose to transition to Exchange 2010.

    If you are upgrading from any messaging system besides Exchange 2003 or Exchange 2000, your only option is to migrate to Exchange 2007."

    Yes, it is possible and supported to migrate from Exchange 2003 to 2010 or keep in coexistence during transition.

    You can also move mailboxes back to 2003 from 2010 if you need to for some unforseen reason. This is great if during coexistence something comes up and you have to back off temporarily.

    Exchange 2003 does not support the "online" mailbox move like 2007 --> 2010 does.

    hi,

    and addtion,

    migration and transition is supported from exchange 2003/2007 but in-place upgrade is not supported.

    can not coexist with Exchange 5.5 and Exchange Server 2000.

    Hi,

    I have migrated our Serves from Exchange 2003 to Exchange 2010. All mailboxes are now running on Exchange 2010 and Exchange 2003 is not needed.

    I can't find any information to "remove the Exchange 2003 after migrating to Exchange 2010". What are the steps or any link?

    Thanks,

    Sher

    While I am not aware of an updated article, I do not believe anything has changed since 2007. This page was updated 9/9/2009 for Exchange 2007 SP2.

    I cannot verify this as being the accurate answer but I do know that in a transition from Exchange 2003 to 2007 you would go through the Exchange 2003 uninstall to remove the Exchange 2003 from email service.  Start-up the Exchange 2003 install CD and remove the application.  I assume that this would also apply to the Exchange 2010 transition too.

    BTW, I can't find a reference now, but it may be worth mentioning that if you are leapfrogging 2007, you may still want to run the 2007 AD prepare tools, so that if, after installing 2010, you have some need to install Exchange 2007, you can.  Otherwise, you will not be able to.  I am trying to find where I got that, but I cannot.  Anyone please feel free to verify that.

    Hi Guys,

     

    currently we have 4 Exchange Servers with 4 Domains in the same Forest.

    We have 3 Exchange Server 2003 Ent, 1 Exchange Server 2000.

    Now, we are planning to separate the 4 domains into 4 different forest each has its own DNS and AD.

    Company A, Company B, Company C and Company D

    currently Company A is our parent domain

     

    We will first separate B [currently on Windows 2003 / Exchange 2003 Ent]

    to Windows Server 2008 with Exchange 2010.

    Will ADMT help me on this scenario?

    - move "specific" users from A to B

    - move "specific" computers from A to B

     

    Hope to hear from you soon.. thanks a bunch

    What if you need to revert back to Exchange 2003 once migrated to 2010?  Some clients always want to have a backout plan, just in case.  My guess is that this would not be highly recommended and am hoping that, in fact, industry best practices would dictate that it is not recommended.  Is that the case?  Is there a link or somewhere I could find a full list (or list) of the errors we would expect to encounter if we did have to migrate back to Exchange 2003 from Exchange 2010?  Any and all help would be appreciated.

    I had the same question so I tested it out. I migrated a user to 2010 and migrated back to 2003 with success. Now I'm sure somewhere out there people have had issues, but it suprisingly migrated flowlessly. It is not recommended to migrate back to 2003 but in my case, it did work.

    Thanks, Jason!  That's comforting to some extent.  Was there somewhere where you pre-identified issues that may come up?

    Cheers,
