  • Moving Mailboxes from Exchange 2000 to 2003

    Greetings All,

    I have a question, We are looking to migrate from Exchange 2000 to Exchange 2003. I have built the Exchange 2K3 Box, joined it to the organization and setup a test email account on the 2K3 server which can send and recieve mail no problem.

    When moving mailboxes from one Exchange box to another, do I have to stop all external mail from coming in as well as making sure NO one is logged on? Or could I do it late at night per say when no one is on and email traffic is minimal??

    What is the best recommendation for moving mailboxes from one Exchange box to another?

    I will also be backing up everyone's email box with Exmerge just incase of any corrupted mailboxes.


    Thanks in advance

    Have you replicated the public and system folders across?
    If not, then you should do that first as it takes a while to come across from Exchange 2000. You will see performance issues if you try to replicate the public folders after the mailboxes have been moved.

    I move thousands of mailboxes every month and I don't do an exmerge backup for any of them. The move mailbox process is very safe - if something fails then the original mailbox is not removed.

    As for mail flow, you do not have to do anything. You can only move five mailboxes at any one time, and Exchange knows the mailbox is being moved and queues the email message. Once the move has been completed the email is delivered.

    I will often do bulk moves during the night. If you use ADUC on Exchange 2003, you can select all of the mailboxes in one go, set it to move them, then leave it to get on with it. The process is multi threaded, it moves five mailboxes at a time and then moves on to the next one. If one has a problem then it it is skipped and you can see which one caused the problem.

    Other users can be online when the mailboxes are being moved - depending on your work pattern you may have times when people are not in the office and you can move the mailbox across.

    Simon.

      Thanks for the reply, So you dont think I should move the mailboxes first, THEN do the replication of the public folders / cut off from Exchagne 2k?? I want as little downtime as possible thats why I figured if I moved all the boxes first then did the replication it would be easier. I only have about 100 mailboxes in our organization, a few users with about 1GB of email the rest 50mb to 100mb..

      How long does it take to move a 1GB email box?

      Also what happens if the user's mailbox i'm moving logs into outlook? Will it screw up the process? corrupt the mailbox?

      I was going by this article here:

      http://www.msexchange.org/tutorials/...-Hardware.html

      and the author doesnt recommend having anyone logged into the system or having email coming in externally.

      Just trying to get the best approach.


      Thanks in Advance

        My business is migrating Exchange servers. I spend most of my time doing them or helping other people do them.

        Public and system folders go across first. Mailboxes are actually the last thing to go across.

        This is my article on the process: http://www.amset.info/exchange/migration.asp

        You are the second person today to refer to that article and I am not very impressed by it. It also pre-dates Service Pack 2 which made the migration process easier with the enhancements to public folder management in E2003.

          Thanks for the help, and the article is great. Yes, I agree that article isn't the greatest they contradict alot of things which is why I wanted a second opinion before I did anything.

          Just one more question, we have BES 3.6 running on another server, so when moving the BESADMIN account I should make sure all the BES services are off and then move the account the normal way. What do you mean by using the "Profile" tool? Is that on the BES server or exchange?



          Thanks

            There is a tool within the Blackberry server that allows you to update the MAPI profile that it uses. You might find that if you shutdown Blackberry, then move the mailbox, then restart the services that it updates. However I find that it doesn't.
            I haven't done a BES 3.6 for a while, I have all of my clients on at 4.0.

              Yeah, we are in the process of migrating from 3.6 to 4.0 now. I started the public folder replication today on:

              -Oraganiztion's Public Folders
              -Offline Address Book (OAB)
              -Schedule + Free Busy
              -Organization Forms


              Once eveything is replicated and running, the next step would be to move the mailboxes first then start moving the services for exchange (RUS, SMTP, Routing Master) to the 2K3 box


              Is this correct?


              Thanks for the help

                I tend to move things like RUS, Routing Master etc to the new server once the old server is sending more than 50% of its email to the new server rather than keeping it. If you are going to be doing the mailboxes in one hit, then move everything across in advance, so that the old server only has the mailboxes on it.
