I’m starting the process of collecting resources to build a plan to finally upgrade an old (but new) Ember 2.18.2 app to… 3.x - haven’t decided if it should be 3.20 or 3.23.
Regardless, can folks point me to online resources covering this (arduous) task? I have already found the Upgrading topic on guides.emberjs.com.
Also, if folks have traveled down this path before, what should I be aware of?
Thank you for your time!
