Last weekend I was trying to upgrade my Unity server 3.1.5 to 4.2.1. The System Preparation Assistant said I needed to install Data Store Service Pack 4. I selected the 'click here link' and the install was successful then rebooted server. Ran the CUSPA again and the same thing, need to install the Data Store SP4. I did this at least 3 times.
Has anyone seen this issue with CUSPA?
