About

MINISTRY OF DEFENCE awarded a contract to Rockstone Technologies Ltd for migration architecture and engineering services related to the rollout of Windows 11 across the Defence user base.

The migration had been delayed by approximately three months while technical and security issues impacting Windows 11 users were investigated and resolved.

Contracts linked to the migration were pivoted to address these issues, and following the restart of migration, EUS realigned several contracts and deliverables against the new rollout schedule.

The contract value is AUD 1,094,337.5.
