Moving points from Snap IO to Epic IO


I am trying to upgrade a customers PAC PRO project from a Snap system to Epic.
So, I added an IO rack for the epic inside the old PAC PRO V10 and/or 10.1 project. My issue is that when I try to copy IO points from the snap IO to the epic IO, I cant. The epic rack doesn’t even show up in the “Select a target I/O Unit” list at all. Does anyone know a way around this? This will make it pretty tedious to migrate larger projects from Snap to Epic. I had hoped to retrofit EPIC’s more than just use them for new builds.
