Payroll Gateway, Database, and Migration Troubleshooting

Summary

This page records confirmed payroll gateway, database, and migration troubleshooting behavior and marks incomplete boundaries explicitly.

Audience

Payroll users, developers, QA and support engineers, architects, and implementation reviewers.

Symptoms

Compatibility behavior differs, the service fails startup, a Payroll route is unavailable, or persistence operations fail.

Cause

Route ownership may be direct/shadow/compatibility, parity may differ, migration can fail startup, migration suppression may be active, or persistence connectivity/model state may be unavailable.

Resolution

Confirm approved route-source/cutover state and health evidence. Compare supported contracts rather than raw payloads. Escalate migration/connectivity issues to the service/database owner. Never run database commands, change migration history, expose configuration, or bypass the gateway during support.

Validation

Use approved health, smoke, parity, and migration verification evidence in a non-production scope. Confirm restored route behavior without creating duplicate Payroll writes.
