I'm performing an Active Directory Forest Migration from one AD forest to another. The tool I plan to use is ADMT V3. This tool according to the documentation doesn’t support Exchange 2003 unless I misunderstood. My strategy for the Exchange Migration is to build a new Exchange Org in the new domain. Use mail contacts in the old domain / exchange org to forward email to new Domain in the new Exchange org then clean up the MX records and point to new SMTP server for new domain. Extract the mailboxes with exmerge from old domain / Exchange Org; import the mailboxes into new domain / Exchange Org. Can someone shed some light on how I can migrate over 50 gigs of public folder data between two Exchange Orgs? Can someone see the approach I'm taking and concur with my logic? Kind regards, John
