Togetha's IRAP-Ready Cloud Migration: Transitioning a $2.25B Government Agency from Legacy Systems to a Secure, Scalable Atlassian Cloud Ecosystem.

Overview

A large Australian Government agency with 4,000 employees and a $2.25B annual budget needed to modernise its aging Atlassian on-premise ecosystem. With increasing security, compliance, and operational resilience requirements, the agency initiated a strategic transition from self-managed Jira and Confluence to Atlassian Cloud.

Togetha was selected as the lead partner to deliver an enterprise-grade migration aligned with IRAP-ready standards, government compliance frameworks, and the agency’s digital transformation objectives.

Key Challenges

• Legacy on-prem systems creating technical debt, security exposure, and high maintenance overhead

• Complex Marketplace apps requiring cloud-ready replacements or re-engineering

• Strict compliance requirements, including IRAP and Australian Government security standards

• Distributed workforce requiring extensive change management and communication

• Minimal internal Cloud migration experience, requiring guided technical and organisational uplift
