  • Upgrade Exchange 2003 standard to enterprise

    Hi guys,
    I read these links:
    http://www.petri.com/upgrading_from_...se_edition.htm
    and
    http://support.microsoft.com/?id=170280

    I know it is just a simple reinstall but I have some specific questions. I use Exchange 2003 standard version 6.5 (build 7638.2 Service pack 2) and a Windows server 2003 32 bit. We've reached 75 GB limit so we need to upgrade it. The problem is that priv1.edb + priv1.stm is almost 82 GB and I have to mount the Mailbox Store almost everyday. My questions are:

    1. Should I do domainprep and forestprep again when I run setup of the enterprise?
    2. Should I dismount Mailbox Store before?
    3. Should I stop TrendMicro antivirus?
    4. I guess there will be no impact of the storage limits and connectors, right?
    5. Long time ago we use this: http://support.microsoft.com/kb/912375. So, should I remove this key before upgrade or after the upgrade?
    6. I think the last one is that I should run SP2 installation package and run Microsoft update, right?

    Sorry to bother you but I need to know the answers before do this upgrade. Thanks in advance.

    your forest and domain are already prepped for Exchange attributes - should be no need to run it again.

    I would definitely stop the AV

    Do not remove the registry key you refer to (at a guess, I'm going to say it's in relation to te size of the mail store ?)

    yes, definitely update the OS as well.

      I would actually go as far as to remove the AV. The Exchange services will restart before you can get the service pack installed, and that can cause problems as most AV products expect SP2.

        Thanks for the replies guys. Yes the registry key is for the mailbox store size, but what about it? I'm worry if the store will be mounted again correctly because it is oversize? And should I keep it mounted during the reinstall? Of course after reinstall I will do a backup and after this create a second mailbox store and start to transfer users in order to reduce the size, the last thing will be to perform an offline defragmentation. I think this will be the right procedure in this case, right?

          Why bother with an offline defrag?
          If you are hitting the 75gb limit but the store is only 82gb then you will gain 7gb. For the downtime involved, it isn't worth it.

          75gb store, downtime could be up to 75 hours - so 3 days. That is total downtime, as the information store service has to be stopped while the process is running.

          Do ensure that you remove the registry entries so that the 75gb limit isn't enforced.

          Simon.

            oh crap! thanks for pointing out that I was wrong simon!

            I didn't realise it was an actual limit preventing it from growing above that size, thought it was more to allow it to be up to that size

              Hi guys,
              So, to summarize all the things:

              1. backup
              2. dismount store
              3. delete key for size 75 GB
              4. reinstall exchange with enterprise CD
              5. reinstall SP2
              6. perform Microsoft Update
              7. Mount store

              correct?

              Actually, Sembee last time I did offline defragmentation it took around 1 hour for every 10 GB

                You were fortunate to get that number for an offline defrag. The usual figure that is worked on is between 1 and 4gb per hour, and therefore for prediction purposes you have to work on the worse case scenario.

                The mailbox database will always remount, even if it is over size, as along as you are on Exchange 2003 SP2, because the limit is a soft limit.

                The limit, whether 75gb or something lower will stop the database from going above that limit without dismounting. You can mount it again if it does go above. I am aware of at a number of sites that have a script that runs on a schedule task to remount the database each day because they don't want to upgrade (to either Enterprise edition or Exchange 2007 or higher).

                Simon.
