I have a 700 user 3300ICP LX controller. What hardware will I need to upgrade it to MCD 4.0? Ive already tried the online and offline upgrade using the SI tool but it kept giving me a "Cant retrieve LOS" error message. It connected to the ICP but just couldnt reach the licensing/options info. I found out that I cannot use the online upgrade going from 6.1 to any revision. But why did the offline not work? Is there a maint command to verify the size of the hdd and RAM? Any help would be greatly appreciated!!
