I have a question. I will be migrating everything using ADMT from one forest to another.
Should I set up exchange 2010 with the same host name as the old exchange 2003 or it doesn't matter?
If I have a different host name for the exchange 2010 will I need to go to each workstation and reconfigure outlook profile to use a new exchange 2010? Is it better to give Exchange 2010 the same host name and what are possible problems that I can have if I give the same name.
According to Microsoft, Active Directory Migration Tool migrates profile to the new forest so I don't have to setup it. Will I have to go to each PC and reconfigure outlook to use new exchange or it will be automatically changed.
