Teams moving off Atlassian Data Center have two broad paths: migrate affected workloads to Atlassian Cloud, or evaluate other products for each function they need to replace. OpenProject is a self-hosted project-management candidate, and XWiki is a documentation and knowledge-management candidate; neither should be treated as a proven drop-in replacement. First identify which products and dependencies your organization actually runs, then test the workflows and migration scope that matter.
What Atlassian’s 2029 deadline covers
Atlassian says affected Data Center subscriptions and associated Marketplace apps expire on March 28, 2029 at 23:59 PST. After expiration, the products and apps become read-only. Atlassian lists technical support, critical security fixes, and connectors to Atlassian Cloud through that date; extended maintenance afterward may be available to certain customers by exception. These are Atlassian’s stated terms, so confirm the current policy with Atlassian before making a transition plan. Atlassian Data Center End of Life FAQ
| Product or service | Included in this end-of-life announcement? |
|---|---|
| Jira Software Data Center | Yes |
| Jira Service Management Data Center | Yes |
| Confluence Data Center | Yes |
| Crowd Data Center | Yes |
| Data Center mobile apps | Yes |
| Atlassian Data Center apps and third-party Marketplace apps for affected products | Yes |
| Bitbucket Data Center and Bamboo Data Center | No. Atlassian says they are not ending under this announcement. |
| Jira Align Data Center | No. Atlassian says it is excluded. |
Atlassian says existing customers are to receive a Bitbucket Hybrid License covering Bitbucket Data Center, Bamboo Data Center, and Bitbucket Cloud. Check the current FAQ for the applicable licensing details. The announced deadline is therefore not a blanket end date for every product in an Atlassian-hosted or self-hosted stack.
The sales deadlines come earlier: Atlassian says new customers could no longer buy new Data Center subscriptions or new Marketplace Data Center apps beginning March 30, 2026. Existing customers can buy new subscriptions, Marketplace apps, and expansions through March 30, 2028, according to the same FAQ. These dates make procurement and expansion plans part of the transition decision, not just the final cutover date.

- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Choose a path for each workload, not for the whole stack
Jira-style project tracking, Jira Service Management workflows, Confluence knowledge bases, Crowd identity dependencies, and source-control or CI/CD systems solve different problems. A replacement for one does not automatically replace the others. Bitbucket and Bamboo are also outside the stated end-of-life scope, so teams should assess their source-control and build pipelines separately rather than assume they must migrate with Jira or Confluence.
- Stay with Atlassian for affected workloads: Atlassian presents Cloud as the path for continued use of affected products and describes migration assistants, app assessment, test migrations, solution partners, and scaled support programs. This may preserve more familiar product workflows, but each app, integration, and customization still needs an assessment. Atlassian migration page
- Replace project management: Evaluate a project-management platform against your Jira issue types, workflows, fields, reporting, automation, and integrations. OpenProject is one self-hosted candidate with Jira migration documentation, but the available documentation does not establish complete migration of every Jira configuration.
- Replace documentation and knowledge management: Evaluate a wiki separately against Confluence spaces, page structure, permissions, macros, attachments, diagrams, and links to issues. OpenProject presents XWiki as the documentation and knowledge-management component of an open-source alternative stack; that is vendor positioning, not evidence of complete Confluence parity.
- Keep other products where they are: For products excluded from this announcement, or workloads that do not need to move, confirm licensing and operational terms directly instead of adding them to a migration project by default.
Shortlist candidates and verify what the evidence supports
| Candidate | Potential role | What the cited material establishes | What to validate |
|---|---|---|---|
| OpenProject | Project management; possible Jira alternative | OpenProject documents an Enterprise on-premises edition and Jira migration resources. Its FAQ directs teams to migration guidance and calls attention to custom-field scope. Installation and operations guide; Jira migration FAQ | Which Jira objects, custom fields, workflow rules, history, attachments, links, and app-dependent behaviors transfer; which need manual recreation; and whether the target deployment meets your operational and compliance requirements. |
| XWiki | Documentation and knowledge management; possible Confluence alternative | OpenProject’s alternative page positions XWiki alongside OpenProject as the documentation and knowledge-management part of an open-source stack. OpenProject’s Jira Data Center alternative page | Import coverage for spaces, pages, permissions, macros, attachments, diagrams, and issue references, plus deployment and support arrangements. The cited material does not establish that every Confluence artifact imports or behaves identically. |
| Atlassian Cloud | Continued use of affected Atlassian products | Atlassian describes migration assistants, app assessment, test migrations, specialist partners, and support programs. Its Ascend announcement described self-service resources for organizations under 1,000 users, FastShift for organizations above 1,000 users, and a Solution Design Acceleration program for organizations over 5,000 users. Ascend announcement; Atlassian migration page | Current program eligibility and service details, app availability, data-location needs, integrations, and whether the cloud operating model satisfies your organization’s controls. |
These candidates are not a neutral, independently verified feature-parity ranking. The available sources establish product positioning and the existence of some migration resources, not that a particular team can move without workflow changes or data loss.

Inventory the environment before comparing vendors
Start with the running systems and the reasons they are self-hosted. Build an inventory for each instance before asking whether another product has a similar feature list.
- Record products, instances, user populations, business owners, and the teams that depend on each workflow.
- List Marketplace apps, app data, customizations, scripts, automation, integrations, APIs, and connections to other systems.
- Map identity and access dependencies, including authentication, users, groups, permissions, and audit requirements.
- Document data residency, sovereignty, regulatory, classified-data, security, and operational constraints that shaped the self-hosted decision.
- Identify the content and context users rely on: records, attachments, history, links, comments, reports, and cross-product references.
- Assign operational ownership for infrastructure, upgrades, administration, support, and incident response in both the current and proposed models.
Atlassian’s migration checklist emphasizes assessing apps early, researching each app’s migration path, planning for data and app data, users and groups, attachments, customizations, connections, integrations, scripts, and settings, and identifying manual work. It recommends a runbook and user-acceptance cases, as well as test migrations. The checklist is labeled 2024, so treat it as planning guidance rather than a guarantee of current product behavior.

Compare candidates on migration risk and operating fit
Use the same evaluation criteria for Cloud and alternative platforms. For every critical workflow, document the current behavior, the target behavior, the transfer method, and the person responsible for accepting the result.
- Define the workload: Separate project and issue tracking, service management, documentation, identity, source code, and CI/CD. Decide which are in scope and whether one or several products are needed.
- Test the workflow and extension fit: Recreate representative custom fields, workflows, automation, APIs, integrations, permissions, and audit needs in a proof of concept. Test the Marketplace apps that matter rather than assuming a similarly named feature is equivalent.
- Measure migration completeness: In a test migration, check records and attachments, app data, users and groups, links, history, settings, and customizations. Mark what transfers, what is unsupported, and what requires manual reconstruction.
- Validate control requirements: Compare self-hosted and vendor-hosted options against geographic hosting, data control, sovereignty, compliance, and security requirements. Ask vendors for details applicable to your edition and deployment.
- Estimate the operating model: Include infrastructure, upgrades, administration skills, support, licensing, training, migration labor, and the cost of running multiple products. The cited material does not provide a neutral cross-vendor total-cost benchmark, so build one from your own requirements and vendor quotes.
- Run user acceptance and plan cutover: Use a written runbook and representative acceptance cases. Resolve ownership for failed or incomplete transfers, user training, rollback decisions, and post-cutover support before scheduling production migration.
Atlassian’s 2024 checklist says organizations with three or fewer instances, six or fewer apps, and fewer than 750 users can likely expect a more straightforward migration. It says many instances, apps, customizations, or more than 750 users point to more upfront planning. These are Atlassian’s heuristics, not a prediction or guarantee for any particular environment; a smaller deployment with complex integrations can still require substantial work.

How to read Atlassian’s migration-success figure
Atlassian’s migration page reports a 95% migration plan success rate for Jira and Confluence, but the retrieved page does not state the date, sample size, calculation method, or independent verification for that figure. Treat it as an Atlassian-reported statistic, not as an independent estimate of the odds that your own migration will succeed. Your environment’s apps, customizations, data requirements, and test results are more useful for judging project risk. Atlassian migration page
