Atlassian Data Center end of life: timeline and next steps
By Manuel Mesmer, CEO
Atlassian has announced the end of Data Center. For Jira, Jira Service Management and Confluence, the self-managed edition reaches end of life on 28 March 2029.
If you run Data Center today, you now have a fixed deadline. And an earlier one that is easy to miss.
&w=3840&q=75)
The key dates
On its Data Center end of life page , Atlassian lists three dates, each at 23:59 Pacific Time:
30 March 2026: New customers can no longer buy Data Center subscriptions or Data Center apps from the Marketplace. Support has been winding down in phases since then.
30 March 2028: Last day for existing customers to buy new subscriptions, expansions, upgrades or Data Center apps.
28 March 2029: End of life. Subscriptions and Marketplace apps expire, and the products become read-only.
This affects Jira Software, Jira Service Management, Confluence and Crowd Data Center, the Data Center mobile apps, and Atlassian and third-party apps for these products. Bitbucket and Bamboo Data Center are not affected, and neither is Jira Align Data Center.
The real deadline is March 2028
Most people look at 2029. The date that matters is 30 March 2028: if you have not decided by then, you can no longer expand your licenses. No additional users, no new apps, no license upgrades. If your company grows or a team needs a new app, you are stuck.
Don't count on an extension. Atlassian only extends beyond 28 March 2029 by exception. A 12-month renewal that runs past the deadline is prorated to 28 March 2029.
What read-only means in practice
After end of life, your data stays readable. But new tickets, pages or changes are no longer possible, and Marketplace apps expire.
Until 28 March 2029, Atlassian still provides support, fixes for critical security vulnerabilities and connectors to Cloud, but not after. Atlassian therefore advises against keeping such instances connected to the internet and recommends backing up your data for long-term access.
What to do now
Work back from March 2028, not March 2029. These are the steps we recommend:
Inventory: Which instances, projects, apps and integrations do you run, and who uses them?
Decision: Where are you heading, and what will you leave behind?
Check your apps: Is there a Cloud version of every app, and does it do the same?
Test migration: A trial migration shows where data, workflows or apps cause trouble.
Switch with a buffer: Plan the move so it is done before March 2028. Then you no longer need to expand your Data Center environment.
Why the decision comes before the technology is the subject of a separate article: Atlassian Cloud Migration: Why the Decision Comes Before the Technology .
Support from Atlassian
Atlassian supports the move with its own offers, including the Atlassian Migration Program, Cloud trials for the length of your Data Center subscription, and dual licensing, which lets larger customers run Cloud and Data Center side by side without paying twice. There are also discounts and credits whose terms change. You will find the current details on Atlassian's Data Center end of life page .
