Teams leaving Atlassian Data Center have two broad choices: migrate affected workloads to Atlassian Cloud or replace them with other products. OpenProject is a candidate for self-hosted project management, and XWiki is a candidate for documentation and knowledge management, but neither should be treated as a drop-in replacement without testing the workflows, integrations, permissions, and data that matter to your organization. First establish which products are actually affected: Atlassian’s stated end-of-life date is March 28, 2029, but Bitbucket and Bamboo Data Center are excluded from this announcement.
What is Atlassian’s Data Center deadline?
As of October 7, 2026, Atlassian says the affected Data Center subscriptions and associated Marketplace apps expire on March 28, 2029, at 23:59 PST. Atlassian says they become read-only when they expire. Technical support, critical security fixes, and connectors to Atlassian Cloud are listed through that date; extended maintenance afterward may be available to some customers by exception. Check Atlassian’s Data Center End of Life FAQ for the current policy and licensing details.

The sales restrictions have separate dates. Atlassian says new customers could no longer purchase new Data Center subscriptions or new Marketplace Data Center apps starting March 30, 2026. Existing customers may purchase new subscriptions, Marketplace apps, and expansions until March 30, 2028, according to the same FAQ.

Products included in this end-of-life announcement
- Jira Software Data Center
- Jira Service Management Data Center
- Confluence Data Center
- Crowd Data Center
- Data Center mobile apps
- Atlassian Data Center apps and third-party Marketplace apps for affected products
Products Atlassian says are excluded
Bitbucket Data Center and Bamboo Data Center are not included in this end-of-life announcement, nor is Jira Align Data Center. Atlassian says existing customers are to receive a Bitbucket Hybrid License providing Bitbucket Data Center, Bamboo Data Center, and Bitbucket Cloud. The details are licensing-policy matters, so confirm the current terms with Atlassian rather than assuming this arrangement applies unchanged to every account.

Which workloads are you actually replacing?
“Atlassian alternative” can mean several different projects. Jira-style project tracking, Jira Service Management workflows, Confluence knowledge bases, Crowd identity dependencies, source control, and continuous integration are not interchangeable workloads. A tool that suits project planning may not replace a service desk or wiki, and a replacement for Jira or Confluence does not automatically replace a code-hosting or build pipeline.
Before comparing vendors, inventory the live environment. Record each instance and its users, then map the workflows people rely on to the products, apps, and systems that support them. Include:
- Marketplace apps, custom fields, workflows, automations, scripts, and other customizations.
- Identity and access dependencies, including authentication, groups, roles, permissions, and audit requirements.
- Integrations, APIs, connections, and links between project records, service work, documentation, and code.
- Data and attachments that need to move, along with historical context, links, and records that may need manual recreation.
- Data-residency, sovereignty, regulatory, or classified-data constraints, plus who will operate and support the destination.
This inventory determines whether the real decision is a suite migration, a product-by-product replacement, or a mixed environment. It also exposes hidden dependencies before they become cutover problems.
How should you compare alternatives?
Compare candidates against the work your teams perform and the constraints that led you to self-host—not just a feature checklist. A useful evaluation covers these dimensions:
- Function: Which specific capabilities must be replaced: project and issue tracking, service management, knowledge management, identity and access, source control, or CI/CD?
- Deployment and control: Can the product be self-hosted, or is it vendor-hosted? Where is data stored, and does the deployment model meet your control and compliance requirements?
- Workflow and extension fit: Can the candidate reproduce the custom fields, workflows, automation, permissions, APIs, integrations, and audit practices in use?
- Migration coverage: Which records, app data, attachments, and relationships transfer? What is unsupported, what must be recreated, and how will users find historical material?
- Operating model and cost: Who handles infrastructure, upgrades, administration, support, training, and migration? Include the work of maintaining integrations and customizations. The available sources do not establish a neutral total-cost comparison across vendors.
Atlassian’s 2024 Cloud Migration Checklist recommends assessing apps early, researching migration paths, planning, preparing runbooks, and running test migrations. It advises accounting for data, app data, users, groups, attachments, customizations, connections, integrations, scripts, and settings, as well as identifying manual steps and preparing user-acceptance cases.
The checklist offers a planning heuristic, not a guarantee: Atlassian says organizations with three or fewer instances, six or fewer apps, and fewer than 750 users can likely expect a more straightforward migration. More instances, apps, customizations, or more than 750 users point to more upfront planning. Your actual complexity depends on the environment and the migration path you choose.
Which alternatives are worth evaluating?
The strongest self-hosted candidates in the available product material address different parts of the stack. Atlassian Cloud is the direct option for teams that want to continue using affected Atlassian products. These paths are not like-for-like substitutes, so compare them by workload.
| Option | Workload it may suit | What is established—and what still needs validation |
|---|---|---|
| Atlassian Cloud | Teams seeking to continue using affected Atlassian products | Atlassian describes migration assistants, app assessment, test migration, specialist solution partners, and scaled support. Confirm app availability, eligibility, and migration scope for your environment. |
| OpenProject | Project and work management where self-hosting is required | OpenProject documents an Enterprise on-premises edition and Jira migration resources. Its FAQ directs users to check the migration guide and custom-field scope; the existence of migration documentation does not establish that every Jira configuration transfers. |
| XWiki | Documentation and knowledge management | OpenProject presents XWiki alongside its product as part of an open-source alternative stack. That is vendor positioning, not an independent finding of Confluence parity or complete import coverage. |
| Bitbucket and Bamboo Data Center | Source control and CI/CD workloads already using these products | They are excluded from the cited end-of-life announcement. Their exclusion does not resolve the future licensing or architecture choice for Jira, Confluence, or other affected workloads. |
OpenProject for project management
OpenProject is a plausible candidate when the requirement is self-hosted project management rather than a wholesale replacement for every Atlassian product. Its installation and operations guide documents deployment and administration, while its Jira migration FAQ points teams to migration guidance and custom-field considerations. Test the specific Jira projects, fields, workflows, permissions, integrations, and historical data your users rely on.
XWiki for documentation and knowledge management
OpenProject’s Atlassian Jira Data Center alternative page positions XWiki alongside OpenProject for documentation and knowledge management. Treat that as a starting point for evaluation, not evidence that every Confluence space, page, permission, macro, attachment, diagram, or issue reference will transfer or behave the same way. Use a proof of concept to test representative content and the links users need to preserve.
Rank #4
Atlassian Cloud for continued use of Atlassian products
Cloud is Atlassian’s stated path for continuing to use affected Atlassian products. The company’s migration page and Ascend announcement describe migration resources and support programs. The announcement describes 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. Confirm current eligibility and service details with Atlassian; program descriptions are not a commitment that a particular migration will be covered or succeed.

Do not wait until cutover to discover which apps, identity connections, or custom workflows are essential. Use a staged evaluation that produces evidence about your own environment:
Recommended Free Tools
- Map each workload and dependency. Assign owners to Jira, service management, Confluence, Crowd, and any other systems in scope. Record app and integration owners as well as the teams that depend on each workflow.
- Choose a path per workload. Decide whether each function is moving to Atlassian Cloud, a self-hosted candidate, or another platform. Keep source-control and CI/CD decisions separate from project-management and documentation decisions.
- Check migration routes and gaps. For each candidate, document what migrates automatically, what needs manual work, what is unsupported, and how permissions, links, and history will be handled. Do not infer complete coverage from the existence of a migration guide.
- Run a representative test migration or proof of concept. Include the apps, custom fields, attachments, integrations, user groups, and content patterns that create the greatest risk. Have the people who use those workflows test the result.
- Write a runbook and acceptance cases. Record sequence, owners, dependencies, validation checks, fallback decisions, and user communications. Define what must work before a workload can be accepted.
- Estimate the ongoing operating burden. Include administration, upgrades, infrastructure, support, training, integration maintenance, and the migration work itself—not only license fees.
Atlassian reports a 95% migration plan success rate for Jira and Confluence on its migration page, but does not state the date, sample size, calculation method, or independent verification for that figure. It is a vendor-reported statistic, not a probability estimate for a particular organization. Your test migration and acceptance results are more useful for judging your own readiness.

How should a team choose?
If retaining Atlassian workflows is the priority, evaluate a Cloud migration early and test app and data coverage before committing to a schedule. If self-hosting is a firm requirement, assess OpenProject for project management and XWiki for knowledge management as separate candidates, then verify interoperability and migration completeness in a proof of concept. If your stack includes Bitbucket or Bamboo, treat those workloads separately: the cited 2029 end-of-life announcement does not include them.
The practical decision is not whether one product can reproduce an entire Atlassian estate in theory. It is whether each destination can support the workflows your teams need, preserve the data and access model they depend on, and fit the organization’s deployment and operating constraints.
