- Validate that Linux-built binaries produce equivalent business outcomes to AIX-built binaries.

- Compare

- Application output

- Database state

- File outputs

- Transaction results
- End-to-end business processes
- Generate structured evidence and reports for migration sign-off.
- Investigate and resolve discrepancies between AIX and Linux execution.
