Win2k3 AD running in 2000 Native mode, 1 (one) Exchange 2000 Server running in Exchange 2000 Native mode
I am ready to upgrade to Exchange 2003 using new hardware .....the new box is running Win2k3 R2 and I've performed all pre-requisites (I think)...eg., InetOrgPerson fix when I upgraded to 2003 AD, made the recommended memory adjustments for Exchange 2003 on the server, run dcdiag and netdiag and analyzed the results, etc..
I plan to use the latest version of ExDeploy for the install....installing the new server by choosing to "Upgrade from Exchange 2000 Native Mode"....if all goes well, I will then have two Exchange servers in the Org, one 2000 and the new 2003. I then plan to move the mailboxes, public folders, etc..to the new server.
We are running OWA as well.
1.) Can I move the mailboxes and public folders a few at a time , or is this an all or nothing process? If they are moved a few at a time over the course a couple of weeks, will internet mail find its way to the correct mailboxes on the new server....will mail flow be interrupted in any way ?
2.) I understand that an SMTP connector is not needed In pure Exchange 200x environments.....but through ESM in the current Exchange setup in the "Connectors" group I see a "Company" Internet Mail connector ?
Bottom line......when the installation is completed and the mailboxes, public folders, etc., are moved, what are the critical points that I need to be aware of to ensure that mail will flow as it did before ?
This is my first stab at this kind of upgrade and any input would be greatly appreciated !
