an Atlassian Silver Solution Partner<\/a>. Our certified consultants support Data Center-to-Cloud migrations using an approach that always begins with an audit of the existing environment before making any changes. <\/p>\nWhat this means for you:<\/strong><\/p>\n\n- An honest assessment of your system<\/strong>: mapping your apps, identifying real risks, and estimating the workload. We won’t make any promises about a timeline until we’ve taken a look under the hood. <\/li>\n<\/ul>\n
\n- A plan tailored to your constraints<\/strong>: we structure the project so that the internal workload remains manageable, with clear milestones and a well-chosen transition window.<\/li>\n<\/ul>\n
\n- Full migration of your workflows, permissions, and automations<\/strong>: You move to the cloud with your instance already up and running, not with an environment that needs to be reconfigured.<\/li>\n<\/ul>\n
\n- Training your teams<\/strong>: Your users will know what\u2019s changing and why before the switchover, not after.<\/li>\n<\/ul>\n
\n- Post-migration support<\/strong>: The first few weeks in the cloud are when questions tend to come up. We’re here to answer them. <\/li>\n<\/ul>\n
Our consultants work on both technical configuration and business practices (ITSM, Agile, project management, ESM), which eliminates the need for back-and-forth communication when a migration decision affects both administration and team processes.<\/p>\n

<\/span>Conclusion: Migrating from a Data Center to the Cloud\u2014Choose Your Timeline Before It\u2019s Imposed on You<\/span><\/h2>\n[\/et_pb_text][et_pb_text _builder_version=”4.27.7″ custom_padding=”||5%||false|false” inline_fonts=”Roboto” global_colors_info=”{}”]<\/p>\n
Migrating to Atlassian Cloud<\/strong> isn’t a project you can just jump into overnight. But it’s also not a project reserved only for teams that have six months to spare and a dedicated task force. <\/p>\nSuccessful migrations all have one thing in common: they begin by cleaning up the Data Center instance<\/strong> before touching anything else. Inactive projects, obsolete workflows, duplicate permission schemes, ghost user accounts, and unused Marketplace apps. <\/p>\nAn instance that has been cleaned up before migration arrives in the cloud in a stable, well-managed state, ready to scale. An instance migrated “as-is” carries its problems into a new environment, and those problems are often more visible and more costly to fix once in the cloud. <\/p>\n
What makes the difference next is preparation. Launch Portfolio Insights<\/strong> to map out your apps. Clean up your inactive users before migrating. Choose your migration window rather than being forced into one. Three concrete actions you can take right now that will radically change what happens next. <\/p>\nYou still have a comfortable window of time ahead of you. Not indefinite, but comfortable. Organizations that begin planning in 2026 can afford to take things in order: assessment, plan, dry runs, and a controlled transition. Those that wait until 2028 will have to migrate under pressure, with fewer partners available and less leeway to handle unforeseen issues. <\/p>\n
The question isn’t “Should I migrate?” You already know the answer to that. The question is “Do I want to choose how to do it, or wait for it to be imposed on me?” <\/p>\n
Start with an assessment. In just one session, we’ll tell you exactly what your migration entails! <\/p>\n

<\/span>FAQ – Migrating Atlassian Data Center to the Cloud<\/span><\/h2>\n[\/et_pb_text][dsm_faq dsm_make_accordion_toggle=”on” dsm_open_faq_item=”on” dsm_enable_schema_markup=”on” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”][dsm_faq_child dsm_title=”What is the deadline for migrating from Atlassian Data Center?” dsm_content=”<\/p>\n
The official end-of-life date for Atlassian Data Center is March 28, 2029. On that date, all Data Center instances will switch to read-only mode: no actions will be possible (creating tickets, updating pages, running workflows). <\/p>\n
There are two interim deadlines to keep in mind:<\/p>\n
\n- March 30, 2028, the deadline to renew or extend your existing Data Center licenses,<\/li>\n
- and March 30, 2026\u2014which has already passed\u2014when sales of new licenses to new customers ended.<\/li>\n<\/ul>\n
” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”][\/dsm_faq_child][dsm_faq_child dsm_title=”How long does it take to migrate from Atlassian Data Center to Cloud?” dsm_content=”<\/p>\n
The duration depends on the size and complexity of your instance. For environments with 200 to 500 users, a few Marketplace apps, and limited integrations, a well-planned migration takes 7 to 12 weeks to complete. <\/p>\n
For more complex environments, with numerous integrations or custom scripts, the timeline may extend to several months. In any case, the preparation phase (audit, cleanup, dry runs) determines the duration and quality of the migration. <\/p>\n
” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”][\/dsm_faq_child][dsm_faq_child dsm_title=”What happens to my Marketplace apps during the migration to the cloud?” dsm_content=”<\/p>\n
Marketplace apps do not migrate automatically. Each app has its own migration path, defined by its publisher. Some apps have a Cloud version with full feature parity, others have limitations, and some do not have a Cloud version at all. App data (custom field values, plugin-side configurations) is not handled by Atlassian\u2019s native tools: it is up to each publisher to provide a migration path for their data. The Portfolio Insights tool (admin.atlassian.com) lets you map out your entire app portfolio and assess their Cloud compatibility before you begin. <\/p>\n
” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”][\/dsm_faq_child][dsm_faq_child dsm_title=”Will my workflows and automations be preserved after the migration?” dsm_content=”<\/p>\n
Native Jira workflows<\/strong> and standard automation rules are migrated using the Jira Cloud Migration Assistant<\/strong> (JCMA<\/strong>). However, ScriptRunner scripts (post-functions, listeners, and behaviors written in Groovy) are not directly compatible with the Cloud architecture and must be evaluated and, in some cases, rewritten. <\/p>\nCloud-native automation<\/strong> has evolved significantly and now covers a large portion of the use cases that previously required scripting in the data center. An audit of your automation workflows before migration helps identify what can be carried over as-is, what needs to be reworked, and what can be replaced by a native rule. <\/p>\n” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”][\/dsm_faq_child][dsm_faq_child dsm_title=”How much downtime should be expected during the switchover?” dsm_content=”<\/p>\n
The duration of downtime depends on the volume of data and the migration method chosen. For a standard \u201clift-and-shift\u201d migration, a window ranging from a few hours to a weekend is generally sufficient for instances of a reasonable size. Since 2026, Atlassian<\/strong> has offered a cloud-hosted migration assistant<\/strong> in early access, which enables incremental transfers and significantly reduces downtime during the final switchover. Scheduling the switchover during a period of low activity (weekends, holidays) remains the best way to minimize the impact on teams. <\/p>\n” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”][\/dsm_faq_child][dsm_faq_child dsm_title=”Should we migrate Jira and Confluence at the same time?” dsm_content=”<\/p>\n
No, and it\u2019s actually recommended to migrate them separately. The rule to follow: migrate Jira before Confluence<\/strong>. If you do the opposite, users imported from Jira during the subsequent import will overwrite the user data already in Confluence Cloud. Migrating both products simultaneously increases complexity and the risk of incidents. A sequential approach, with full validation of Jira before starting Confluence, is safer and easier to manage. <\/p>\n” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”][\/dsm_faq_child][dsm_faq_child dsm_title=”What is the difference between Atlassian Cloud Standard, Premium, and Enterprise?” dsm_content=”<\/p>\n
The three Cloud plans differ primarily in their advanced features and administrative capabilities. Standard covers common use cases with limits on automations and storage. Premium adds advanced features (advanced roadmaps, archiving, analytics, priority support) and higher automation quotas. Enterprise is designed for organizations with complex governance needs: multiple instances, centralized administration, enhanced SLAs, and Atlassian Guard included. The choice of plan depends on your number of users, your automation needs, and your compliance requirements. An audit of your current usage will help you choose the right plan without overpaying. <\/p>\n
