FAQs

Q: How often should mainframe systems undergo maintenance?

Maintenance frequency depends on system usage intensity, change windows, and compliance requirements. We typically recommend quarterly routine checks and controlled minor updates, with more comprehensive maintenance performed annually.

Q: What are common challenges in mainframe application support?

Key challenges include compatibility with modern operating systems, integration with cloud-native applications, a shrinking pool of mainframe-skilled professionals, and meeting evolving security and compliance standards across Australia and APAC.

Q: Can mainframe support include data migration to modern platforms?

Yes. Our mainframe services include planning and executing data and application migrations to modern cloud or hybrid infrastructures, ensuring data integrity, system compatibility, and minimal operational disruption.

Q: How does mainframe support contribute to disaster recovery?

We develop comprehensive disaster recovery strategies including automated backups, system redundancy, and documented recovery procedures to restore mainframe operations quickly if systems are compromised or disrupted.

Q: What are the benefits of outsourcing mainframe support?

Outsourcing provides access to specialised mainframe expertise and tools that are increasingly difficult to maintain in-house. It allows your organisation to focus on core business objectives while experienced engineers keep infrastructure reliable.
