For osTicket alternatives, build a test inbox that mirrors how requests arrive and are assigned.
- Create tickets by email and web form; test attachment handling and spam controls.
- Route by department, priority, and agent availability.
- Verify customer replies, internal notes, SLAs, and escalation alerts.
- Export a resolved ticket with its full thread and audit trail.
- Test permissions and reporting with agent and supervisor accounts.
A ticket migration is successful when no request loses ownership. Run the two systems in parallel until intake and response totals match.
