As our Dev version is 12.0 and Prod is 11.3. We are unable to migrate applications from DEV(latest version) to PROD(older version). Please provide solution for the same.
Due to schema change between DE 11.3 and r12, you cannot export/import applications across different DE versions (from Dev version 12.0 to Prod 11.3 and vice-versa).
CA Workload Automation DE (dSeries)
Upgrade the Prod DE instance to the same version as your Dev DE instance. This will allow you to export and import applications across DE versions.
