Ha, yep you've got a good path laid out to know when to panic! I'm going to run both my current Apex system alongside my new Profilux, mainly because I have way too much $ invested in Apex at the moment to try to emulate with the Profilux, but I am going to switch over some of the vital functions from the Apex to the P4, and honestly will probably transition over to the Profilux piece by piece over the coming years. I used to manage an oilfield automation team for work, and we used ~$15k controllers to run our facilities, and in my opinion the Profilux is very similar to those in build quality and the software interface, so I would feel better having the foundational controls handled by the P4.
