In EPM 11.1, we used App Copy utility to copy application between environments but in EPM 11.2, Oracle is recommending only LCM as the process to migrate applications.
So, we selected all the artifacts of App-1 from Environment-1, exported using LCM to a network file system, copied the file to the network files system of Environmnet-2, and imported the artifacts in the order Application Snapshot -> Application Definition -> Remaining artifacts into a newly created shell application App-2..
After the migration completed after 6+ hours, there was no data in the application App-2.
Kindly advice, if we are missing any steps in the migration process.
