I'm in the planning phase of migrating a PI OPC DA Interface to a newer ReadOnly version. The only information in the user guide is a link to Live Library that has a 9 step approach. However on the final step where it instructs you to start the interface, there seems to be a gap of information in regards to what to do with the existing interface apart form uninstalling it once you're finished. My main concern is there will be 2 interfaces with the same pointsource and interface ID running simultaneously. Will PI handle running 2 interfaces with the same pointsource and ID for a short period of time without doubling up values while I transition from one interface to the other?
