Copying an existing Exchange configuration to a new server

SearchExchange.com expert David Sengupta explains how to back up the directory store and information store, and then restore it to a new server.

I am going to move an existing Exchange 5.5 SP4 server from its current server to a new server. Both servers are Windows 2000 with the latest service packs and hotfixes. The new server is in an isolated network, so I can have the exact same name and configuration as the current one.

Is it possible to use NTBackup in Windows 2000 to back up the directory store and information store, and then restore it to the new server? I have done the backup and restore, but when I use the Exchange administrator tool to open the address book, it doesn't show any mailboxes. It looks as if I haven't done any restore.

You will want to make sure you run ISINTEG -Patch in order to restamp the information store with the proper GUID prefix. It's not just the servername that's important. While the servers may share a name, their GUIDs are different.
