I currently have a voicemail only Unity server running version 4.0.3 with Exchange 2k running on the same box. I am looking into how to safely separate Unity from the current box and reinstall it onto a new box while still keep Exchange 2k on the current box as the message store, I understand that I have to use DiRT backup to backup Unity data on the current box and then install Unity on the new box and restore Unity data from backup. I would like to find out if I can bring up the new Unity server first, make sure all is working and tested before uninstall Unity from the current box.
Has anyone done this before ? Any inputs is highly appreciated !!!
