The art of moving off of an A/B Test system

At Calm, as I assume is similar with many consumer tech companies,
experimentation is a way of life. At the time of writing, I’m in the process
of moving Calm away from not only our first in-house experimentation system,
but our first external system. I don’t claim to be a SME in many things, but
when it comes to deprecating old A/B test systems, I’m somewhat of a pro.
