I have done an inplace Upgrade from Windows NT4.0 to Windows 2003.The Upgrade is smooth.
Now I have to migrate from Exchange 5.5 (on NT) to Exchange 2003 (on Win2003).I have installed Exchange 2003 Server in the different Orginisation. I have two exchange 5.5 Servers in the Production Environment Front end and the Backend.First I used ADC to move the Mailboxes from Exchange5.5 Backend Server to Windows 2003.
After that I tried use Migration Wizard to Move Mailboxes from Exchange 5.5 to Exchange 2003(on NEW Organization).
But when I run Exchange server Migration Wizard I get the following error: ” Invalid server specified or you do not have permission required to complete the operation”. And occur the event id 7048 with the source MSExchangeMig.
The account that I’m using is the administrator account on Exchange 5.5.It is the member of Enterprise admin,Schema admin,DomainAdmin and Exchange service account.
