Atlassian Data Center Migration Readiness Checklist
Key Takeaways
- Start with scope, not urgency: confirm the environments, owners, and exceptions that are actually in scope.
- Apps and custom logic drive effort: review Marketplace apps, automation, and ScriptRunner work together.
- A credible plan includes governance: identity, compliance, commercial impact, and ownership decisions matter as much as data movement.
Review Your Migration Position
If you already run Atlassian Data Center and want a clearer view of timing, constraints, or migration options, we can help you review the situation.
A useful migration checklist should make the work clearer, not make the deadline feel louder. Before teams commit to a timeline, they usually need a better view of the environment they already have, the constraints they cannot ignore, and the work that will actually drive effort.
1. Confirm The Environment Inventory
List the Jira, Confluence, and related instances that are truly in scope. Include users, projects, attachments, integrations, and ownership. Many plans drift early because teams underestimate how many exceptions and side systems they are carrying.
2. Review Apps And Custom Logic Together
Do not assess Marketplace apps separately from custom workflows, ScriptRunner logic, or automation rules. Those choices usually drive the hardest redesign work.
3. Clean Up Data Before Sizing The Move
Archived projects, inactive users, stale attachments, and obsolete spaces affect both migration complexity and cloud cost. A smaller, better-governed dataset usually produces a more realistic plan.
4. Validate Identity And Access Assumptions
User directories, group models, SSO expectations, and admin ownership should be reviewed early. Identity issues create avoidable disruption when they are discovered late.
5. Model The Commercial Picture Honestly
License structure, Guard, storage, app subscriptions, and transition-state overlap costs should be understood before leadership sees a final recommendation. This is where many "simple" cloud moves become more nuanced.
6. Check Compliance And Residency Requirements
If the environment carries healthcare, public-sector, sovereignty, or internal control constraints, validate those assumptions before committing to sequencing.
7. Decide Who Owns The Plan
Most delays are not purely technical. They come from unclear ownership, split budgets, or a mismatch between program intent and operational reality. The checklist is not complete until decision ownership is explicit.
In our migration planning work, the most valuable early output is usually not a launch date. It is a more honest view of effort, risk, and sequencing.
Review Migration Readiness
If you want a clearer picture of what will actually drive effort in your environment, we can help you review the readiness gaps before they turn into timeline surprises.
Schedule ReviewTurn the checklist into a migration-readiness decision
Use this article with the Data Center EOL guide when you need to decide whether your Jira, Confluence, JSM, apps, users, and integrations are ready for Atlassian Cloud planning.
When should an Atlassian Data Center customer start migration planning?
Start planning as soon as product scope, renewal timing, app dependencies, identity requirements, and business owners can be confirmed. Complex Atlassian environments need time for discovery, test migrations, app decisions, and user-change planning.
What should be included in an Atlassian Cloud readiness checklist?
A readiness checklist should include products, users, groups, permissions, Marketplace apps, custom scripts, automations, integrations, data volume, security requirements, data residency, validation owners, and cutover constraints.
