Jira "Next Gen" integration with CA PPM?

[Deleted user]

We are in the process of integrating Jira and CA's PPM tool.  However, we are using mainly "Next-Gen" project in Jira for all of the features that are currently released and on the roadmap.

Has anyone done an integration using "Next-Gen" projects? 

How did it go? 

Is there missing data that you just could not get out of "Next-Gen" projects?
