We'are going to install an off-box 2000 unity which will connect to existing 5.5EX. What's the best solution, joining the existing 5.5 when installing the forestprep or creat new OU then install ADC later? What's the major difference ? Thanks
In that environment you want to point Unity at the Exchange 2k box, then the 5.5 boxes will talk with the 2k box on the back side. You cannot connect Unity to the 5.5 site, then move it to the new 2k box.
No, in this moment we are not migrating exchange 5.5 to exchange 2000. We just want install a new Unity with exchagne 2000 off-box installed, and this unity will connect to existing 5.5. By the way, customer doesn't have any ex2000 yet. In terms of connecting EX2000 with ex5.5, I think there are two ways, one way is to select join the existing exchange OU when install the forestprep, the other way is to create a new exchange OU and then install ADC to connect it with existing change 5.5 OU. Which way is best? Thanks.
Unity does not require Exchange 2000. In my opinion, Exchange mixed mode is complex, problematic and something that should be avoided if possible. If you are not migrating Exchange 5.5 to 2000 you really don't want to run mixed mode. Trust me.
To upgrade from Exchange 5.5 to Exchange 2000 you need to install the ADC and setup connection agreement(s) first. No way around that. You dont need to make a new OU for Exchange. Once you have the ADC connection agreement(s) setup and replicated you can run /forestprep.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
