We just installed first Exchange 2003 server. It coexists with old Exchange 5.5 (which is also a domain controller). AD is on a new 2003 box. We moved 3 unimportant mailboxes to the new Exchange for testing, and planning to gradually move the rest. Now the question: WHEN should we use pfMigrate.wsf /S:OldBox /T:NewBox /A /N:100 /F:C: \logfile.txt and pfMigrate.wsf /S:OldBox /D: NewBox /D if we would like to make sure that Public Folders are online, and available at all times to both (old and new) mail server users? Thank you.
