    Hi,

    Exchange server is on exchange 2003 on windows 2003 R2. 

    1.      I had an architecture of parent & child domain controllers, Where parent company is closed Down. But we have an additional Domain Controller of parent DC in our premise.
    2.        Due to this fact exchange organization is also unavailable & cannot make modification on my exchange server configurations (Global Settings, such as changing recipients attachment restrictions, everything is grayed out).
    3.        Is there any way where we can have staged migration. I mean can I keep old & new server running together & keep few users on new Exchange organization & rest of them be on an existing server itself. (I tried testing this too, but email delivers to mailbox store, so, it checks a name & say “Mailbox not available”)
    4.        If I create a new domain environment, I have challenge of migrating users (This I can achieve with ADMT, but actual story starts with mailbox migration)
    5.        Real pain is, I have more than 500 users, can I achieve direct migration over a weekend. (few are POP & OWA users, around 50)

    Can anyone help in this please.

    So, you have exchange 2003 which is inaccessible! Database files .EDB and .STM is there, but Mailboxes are not available.

    And you are planning to create new environment (As you don't have any other option).
    This is a cross forest migration. Which exchange you are planning to install in new environment? I would suggest 2013.

    The only available option you have (As current environment is Inaccessible), Export the PST from EDB files.
    Create Mailbox on Exchange 2013 and Import the PST.

    Do you have Public Folder Database?
    If yes, apply the same process on it.
