I want to upgrade from Exchange 5.5 + SP4 installed on Win2K Domain Server Controller + SP3.
I have another domain controller in the same domain.
Are they enough for In-Place upgrade or I need another new Domain with a new PDC?
I'm confused from the ADC, I don't know where to install it, in the Excahnge 5.5 server computer which is the main domain controller or in the other domain controller, or in a new PDC in a other domain!!!
