Hi, I am getting ready to migrate about 400 users who are currently on Exch 2000 to a new Exch 2003 server. I am somewhat familiar with the procedure for moving mailboxes when both servers are in the same forest or LAN e.g. using the "exchange 2003 move mailbox wizard", but I have a slight complication. The old Exchange 2000 server is in a different city, it belongs to a completely different organization, we have no Administrator access to it and there is no feasibility of having any direct connection with it. This old Exchange 2000 server also hosts many other organizations and the current hosting company will not want to give us direct access to that Exchange 2000 server. And the data size is substantial, somewhere between 10GB and 20GB total. I have read up on the documentation such as: http://www.msexchange.org/tutorials/Migrating-Exchange2000-Exchange-2003-Hardware.html http://www.msexchange.org/tutorials/Exchange_2003_Move_Mailbox_Wizard.html The admins at the old Exchange 2000 server are willing to export whatever data we need to a USB drive which they will ship to us. So what should I tell them to export to the USB and how? I would like to get the mailbox contents, the PST files, the shared calendars, shared public folders, global address lists, and distribution lists. And once I have the USB drive, what is the best way to import the data? TIA for your help! best regards Mike.
