Hi, we are currently running an OPC DA interface connected to our PI data archive. We would like to switch to HDA as we are having a total upgrade. I would like to know if its possible to connect an OPC HDA connection at the same time and change over each pi tag source to the new HDA connections at our leisure, keeping the pi data already collected by the old DA interface. Switching over all at once would take a lot of resource to rebuild reports/etc, and would like as little down time as possible. Thanks
