No, an app generated in ODC using Mentor cannot be imported to run directly on an on‑premises O11 environment.

ODC and O11 have different underlying architectures (ODC is container/app+library–based, O11 is 3‑tier with modules/apps/solutions), so there’s no supported “export from ODC → import into O11” path similar to OML/OAP/OSP in O11.

What you can do instead is:

1. Treat O11 as the “system of record” and expose its data/logic (via REST or, on the ODC side, via Data Fabric). Mentor-generated apps in ODC can then sit on top of that O11 data and logic. Connecting O11 and ODC: A Live Demo of Secure, Bidirectional Interoperability
2. Re‑implement key parts in O11 manually, if you really need an O11 version:
   • Use the ODC app as a blueprint (data model, flows, UI).
   • Recreate entities, screens, and logic in Service Studio on O11.

In other words, interoperability is supported (O11 + ODC working together), but not cross‑platform portability of apps themselves, including those generated by Mentor.
