Are you migrating existing LiveCycle applications to LiveCycle ES2?
Check out the recent  captivate recording I put together:
  • Importing an 8.x LCA and verifying functionality
  • Making minor edits to resources and pushing them back to the legacy repository
  • Full upgrade/migration of the application to ES2 application model, taking advantage of the new tooling

Full documentation for migration of applications can be found here:

Cheers,
