Hi,
I am going to migrate exchange server 2003( dc : server 2003 ) in one forest to exchange server 2010 in another forest (dc: windows server 2008 R2), since it's not possible to create trust relationship between the two forests. Mails/mailbox/information
store all the existing settings/data need to be migrated manually.
So, it's gonna be great help if you please reply with the detail procedure of such migration.
Thanks more in advance.
