Restoring a MS Backup of Exchange 2000 Store into a Exchange 2003 server fresh install

I have been trying to upgrade a 2000 Exchange Server to 2003 Exschange Server and had to give up. I now have about 20 hours to complete the upgrade process and have decided to do a total un-install of 2000 Exchange and install a fresh copy of 2003 Exchange in the hope I can restore the Information Store from 2000 Exchange I have made.

I have already done the forestprep and domainprep before taking the backup if that makes a difference. The OS is Windows 2003 Server.

Is it a simple process? Any help would be appreciated.

Hi andrew_2706,

That is not going to work.

To restore the databases, you will need exactly the same version, and service pack level.

If you are really getting pressed for time, I would simply purchase PowerControls and export directly from the EDB files (assuming that is what you have) http://www.ontrack.com

Another way would be to build another server (use virtual server if you have to) with the same server name, domain name, org name, site name and then try to restore the data onto that

Hope that helps,

I've just had a look at the PowerControls software and it says it wont work with more that 100 mailboxes, there are about 150+ here sadly....

Given that Exchange 2000 is working at the moment on the Windows 2003 Server (though I dont think it should be) I'm going to have to try and do some sort of upgrade but have not managed up to press as i cant get rid of SRS and the upgrade wont work with it there... been on this now since Friday afternoon! I'll have to open another help topic so you get the points though.

Thanks,
Andrew.

Wait, I think I misunderstood you.

If you currently have the exchange server up and running, and can access the mailboxes - you can use Exmerge to get all the mailboxes out (if you are having problems doing a direct upgrade - which I don't really like anyway)

Exchange 2000 on Windows 2003 is not supported, but it can work the way you are doing it (although, i wouldn't rely on that for very long)

I can see Sembee has been trying to help you with the upgrade as well.

As you have the stores up - exmerge them out to PST files - that way no matter what happens, you still have everyones emails backed up, (be sure to get the Public Folders too if you use them)

Looks like you are in all kinds of a mess.  I would seriously be looking at doing the above, and wiping the server so you can start again.

I have just got the Exmerge wizard started and am going to do what you suggested. Thanks a lot to press!
