We are currently running PI AF 2016 (184.108.40.20644) with PI Notifications services 2012. I am looking to upgrade to PI AF 2018. At the same time I am looking to move to a new server. I have a few questions on how to go about this. Is it best to install the old PI AF 2016 and PI Notifications 2012 on the new server and get it moved over first and then install the upgrade? If I install PI AF 2018 on the new server after that, will it migrate the old PI Notifications at that time?
