  • migrating exchange 2k3 between forests

    I'm in the process of tesing migration of one domain to another, I am able to move user, groups and computers using ADMT but when I move the exchange server computer acount across to the new domain the Microsoft Exchange System Attendant service fails to start and I can't figure out why.

    I've hunted high and low on the web but can't seem to find a guide to migrating from one domain to another when exchange is envolved and what affect this is going to have on exchange.

    Can anybody help me out?

    The reason you haven't found anything is because you cannot pick up an Exchange server from one domain and move it to another one.
    You have to extract all the content using exmerge and then import it in to a new server - or the old server has to be wiped and reinstalled when connected to the new server.
    The Exchange databases and general configuration are very closely tied to the Active Directory domain and the server has to be installed in the domain it wishes to be a member of for it to work correctly.
