The end of life for Atlassian Data Center products is planned for March 28, 2029. This milestone reflects Atlassian’s continued focus on Cloud as its future platform — driving faster innovation, enhanced compliance, and AI-powered collaboration.
Key phases and dates
Atlassian has announced the end of life (EOL) for Data Center products by March 28, 2029. The transition will take place in the following stages:
December 2025: Development focus shifts entirely to the Cloud platform.
March 2026: New organizations start with Cloud (existing Data Center customers retain full expansion rights).
March 2028: Data Center sales conclude as Cloud becomes the sole offering.
March 2029: Data Center instances go read-only → End of Life
Atlassian continues to accelerate its cloud-first strategy, focusing innovation on faster time-to-value, reduced costs, AI-enabled teamwork, and enterprise-grade compliance. For customers, this means future innovation will be centered on the Cloud, while the Data Center enters a steady maintenance phase.
With the right preparation, your transition can happen smoothly, at your pace, and with maximum business value.
Atlassian Ascend to the Cloud
This is a significant shift for Data Center customers. To support customers on this journey, Atlassian introduced the Ascend program — a comprehensive set of resources, incentives, and expert guidance designed to simplify the transition to Cloud. Ascend offers transparent pricing, extended support, and migration assistance for Data Center customers, enabling organizations to transition at their own pace while maximizing value from Atlassian’s cloud innovations.
