Considering that I’m working on this as time permits, I think I’ve got a good bit of work done thus far. I have a functional base Plugin framework, and I have started on the UI that will be used to collect the information on what will be migrated. I have built the Packages and Environments UI to allow you to determine what comes from and goes where with what package.
Yesterday I started on the Staging form which is where you will determine what elements go into what package (Form, Filter, Field, etc).
Truly enjoying building this out and hope that everyone will find it useful.
