Goal. To migrate Ex5.5 mailboxes and NT4 domain users to a NEW DOMAIN
and Exchange 2003.
So we have two forests right? There is already a 2 way trust in
place.
Mistake. When installing Ex2k3 the existing Ex5.5 org was joined.
This proved to not work since we are trying to go to a new domain.
Roll back. E2k3 was uninstalled and so was ADC. setup /removeorg was
used to clean up AD of the e2k3 install. ADSI edit was used to remove
the Ex5.5 org name from AD.
Start over. E2k3 was re-installed into a NEW exchange org. ADC was
re-installed.
New Problem. The ADC connection agreement wizard will not complete.
I want a connection agreement so that mail will flow to both exchange
environment while we slowly move users over.
Error: The organization o="NewExOrg" is already installed into this
forest but the configured 5.5 server is a member of organization
o="Ex55org". Please choose a 5.5 server in the correct Org.
Help me Obi Wan Kenobi, you'r my only hope....
