Atlassian will discontinue all Data Center products on March 28, 2029 —support, security updates, and active use will end. Whether on-premises or in a private cloud: Based on JetBrains YouTrack, we’ll work with you to develop a path that meets your needs, ensuring your solutions remain stable, secure, and scalable in the long term.
From that point on, the systems will only be available in read-only mode—without support, without security updates, and without the ability to actively use them.
What this means for youInstead of short-term stopgap solutions, we help you develop a sustainable strategy in a timely manner—one that is tailored to your regulatory, technical, and economic conditions.
Are you looking for a true on-premises alternative to your current Atlassian stack? JetBrains YouTrack offers a powerful platform—but how smooth is the transition in practice? This white paper provides you with impartial and technically sound guidance to help you make a decision. We introduce the system, analyze the challenges of a switch, and offer concrete guidance on migration: What do you need to consider? What steps are necessary? Where can you take action yourself, and where does it make sense to bring a partner on board?
We'll walk you through, step by step, how to navigate this transition in a structured way.

Not every Atlassian environment can be meaningfully migrated to the cloud. Depending on your use cases and regulatory requirements, a platform like YouTrack may be the better choice. We’d be happy to work with you to develop a viable alternative based on YouTrack.
Your Benefits and Opportunities
Migrating legacy systems is rarely a straightforward process. With an approach that flexibly adapts to the complexity of your environment, you always remain in control. Standard importers quickly reach their limits, especially when dealing with complex Confluence structures, nested tables, or custom Jira workflows. Our solution goes far beyond that.
A successful migration requires a clear plan and a well-defined approach. If moving to YouTrack is the right step for you, we’ll guide you through the process with a structured approach—from analysis to adoption—driven by our specialized in-house developments and the clear “Content First” principle:
We analyze your Atlassian environment and identify dependencies, usage patterns, and opportunities for optimization.
Based on the results of the analysis, we develop a customized migration strategy that takes your specific requirements into account.
If a standard Jira feature or third-party plugin is not natively available, we’ll bridge the gap right from this phase. As one of the most active app developers in the JetBrains ecosystem, we develop tailor-made custom apps as needed (such as current solutions for test management or resource management and planning).
Our migration experts will migrate your data to YouTrack securely and efficiently. We communicate transparently and minimize downtime. To prevent data loss where conventional importers fail, we use specialized technologies:
Based on our experience with numerous successful enterprise migrations, we have developed our own comprehensive script library. These scripts allow us to accurately convert your historical data—including ticket histories, work logs, attachments, and links.
Knowledge management, in particular, is considered a hurdle. Our scripts ensure that your content is transferred logically and completely. When starting the migration, the rule is: substance over aesthetics.
Together, we'll optimize your new YouTrack environment and—as needed—build up your internal expertise through customized workshop-style training sessions for administrators and power users.
Upon request, we can provide long-term support and optimization for your YouTrack instance.
As a YouTrack Consulting Partner and Atlassian-to-YouTrack experts, we guide your company and support you in meeting the current demands of modern digital collaboration.
