After reading various blogs on how OAH aka Rosetta 2 operates. I don't see a way to force OAH to recache or delete the .aot files. These file reside in the SIP and the process to turn it off is more involved than a simple reboot. I recommend this blog https://ffri.github.io/ProjectChampollion/part1/ as it provides a good explanation and Part 2 covers attempts to reverse engineer Rosetta 2.
I am not currently having any problems switching between the LIVE and TEST servers. I am also not having any problems running updates on the LIVE and Test servers and the loading a campaign.
