Oracle ODI migration/upgrade from 11.1 to 12.2

I need my existing Oracle Data Integrator 11.1 setup moved cleanly onto ODI 12.2. The current 11g repositories contain a mix of Mappings/Interfaces and several Packages with embedded Procedures; those objects must be upgraded without losing any logic or scheduling detail.

Your first step will be to review both the master and work repositories, catalog all objects, and run the ODI Upgrade Assistant (or equivalent scripted approach) in a non-production clone. Because I’m unsure whether custom Knowledge Modules or hand-tuned performance settings were introduced over the years, I’ll need you to:

Gap analysis
Upgrade or migrate
Documentation handover

Once the assessment is complete, proceed with the actual migration, validate object execution, and unit-test a representative data flow in 12c to prove parity with 11g results. I expect a concise migration report, updated scenarios ready for scheduling, and rollback instructions should we need them.

I have access to the necessary middleware binaries, database schemas, and test environments; just tell me what else you need and the timeline you foresee.
