Hello, My company was recently involved in a merger. Prior to the merger we were in the process of migrating to exchange 2003 from 5.5. I now have the responsibility of collapsing the new companies 5.5 org into our current 5.5/2003 org. Am I able to setup multiple ADC's? Basically one ADC for current 5.5/2003 organization and another ADC for the new 5.5 organization? Thanks for your replies!
