Fastcall is working in a new listing associated to a new managed package. Good opportunity to start with packaging 2. So we are exploring it, and successfully created some test packages v2.
The feature looks great, and we found It can really help us to automate our packaging creation process.
We found that the packages created are not listed in the AppExchange packaging tab, event after promoting to managed release, and linking the dev hub org to the AppExchange organizations. This maybe because the feature is in beta?
So given this, we should start with packaging 1, but not sure if It will be possible to do the upgrade in the future.
@Richard Rosen - It will take 2-3 releases to get to a stage where managed packaging 2 has feature parity with packaging 1 and is listable on AppEx. Until then, you can use Packaging 2 for internal development and Packaging 1 for distribution to customers.
We are working on capabilities to migrate package 1 packages to package 2. When that is available and when Packaging 2 is GA with full feature parity, you will be able to migrate your Package 1 packages to Package 2.
