dear all
I'm planning an exchange 2007 installation in my organization.
Unfortunately actually we have an exchange 2003 on DC and we want to install
exchange 2007 on a different machine and plan a coexistence with Exchange
2003 and Exchange 2007 for some time.
When I'm running
setup.com /PrepareAD
on my DC (unfortunately with exchange 2003) there is an error:
"A previous version of Exchange Server is already installed on this
computer. Run Exchange 2007 Setup from a different computer or remove the
previous version of Exchange Server."
how can i proceed?
thank you for your help
