    New Domain

    Looking at building a new domain, the only thing which is worrying me (a little) is our exchange server. Running MS Exchange 2007 - As we will be changing our internal domain name.

    We will not be affecting our FQDN / email domain which our exchange server is running on yet unsure if i should drop the exchange server from the old domain and then add to the new one? Unsure if / how server trusts are set up.

    Mailboxes aren't set up automatically yet it's sync'd with AD in some way.


    It's a grey area for me, I've got experience of administering exim as a MTA which doesn't seem very useful in this environment!!


    Thanks guys,

    Andy

    If you are changing your internal domain name then you will need to migrate the mailboxes over a domain trust to a new install of Exchange 2007 or 2010 as only exchange 2003 is able to handle a domain rename operation and it is not a pretty procedure. It is probably easier to start fresh on the new domain and migrate anyway given what I have read about domain renames.

    establishing a new domain trust is hopefully the method that we will use - starting a fresh on our exchange server / for all user mailboxes wouldn't be feasible for us... Just need to find a `quick` how-to on the domain trust procedure!!

    You could always export all the mailboxes using exmerge then start from scratch again and simply attach the pst file to all users once its done.

    Hi Zag, sounds a simple way of recreating all our accounts - yet was hoping it would be simpler to just move the current exchange server over to our new system / rebuilt domain.

    Perhaps it would be easier to rebuild the server with the same domain name?

    I agree with the exmerge way to go as easier and attaching the pst is really easy when accounts have same username.

    Unsure the location of any PSTs? We use web access to access our mail boxes (exchange really isn't a strong point for myself - thank you for all your support)!

    You use exmerge to make the pst's for each user,use ExMerge to run stage 1 of a two-stage ExMerge procedure to export all mailbox data to a .pst file on a shared network drive.
    Make sure you have enough space as our emails came out to be about 90 gig .Delete current mailboxes , reinstall new exchange server with trust, create new empty mailboxes under new exchange, import pst's to empty mailboxes.Job done.

    +1 for exmerge as well. To avoid weird things i would never move the same exchangebox to a new domain.

    bio, what if I were to build a new server - prepare the domain for the new PDC then demote the old one? Think this would avoid possible quirks?

    That will work with no problems at all....but then you will not change the internal domain name....
    The quickest way is to create a new domain with a new internal domainname and migrate all AD objects etc.......then use exmerge to export mailboxes and create new exchange organisation and import mailboxes via exmerge.

    "create new exchange organisation" - could you explain this? Just an OU within AD? Really a beginner when it comes to managing exchange, let alone a domain / server transition!
