Atlassian Cloud Migration Explained: What Actually Happens Behind the Scenes

Atlassian Cloud Migration Explained: What Actually Happens Behind the Scenes

February 04, 2026

Atlassian cloud migration is more than moving data from one environment to another. It involves detailed planning, technical validation, security checks, and user readiness activities that happen in stages. Many organizations underestimate what occurs behind the scenes during this process. Jira, Confluence, and other Atlassian tools behave differently in cloud environments compared to server or data center setups. Understanding these changes helps teams reduce risk, avoid downtime, and maintain productivity. This guide explains the real technical and operational steps involved in an Atlassian cloud migration, focusing on what IT and business teams should expect at every phase.

 

Evaluating current Atlassian environment before cloud migration

Before any migration starts, teams must fully understand their existing Atlassian setup. This assessment ensures compatibility, reduces surprises, and shapes the migration approach. Jira and Confluence instances often contain years of configurations that must be reviewed carefully.

  • Inventory of projects, spaces, and users
    Teams identify all Jira projects, Confluence spaces, and active users. This helps determine migration scope and data volume.

     
  • Review of custom configurations and workflows
    Custom workflows, fields, and schemes are analyzed for cloud compatibility. Some server features behave differently or need redesign.

     
  • App and integration assessment
    Installed apps are checked for cloud availability or alternatives. Unsupported apps require replacement planning.

     
  • Data quality and cleanup analysis
    Unused projects, old issues, and inactive users are identified. Cleaning data reduces migration time and risk.

     
  • Infrastructure and performance baseline review
    Current performance metrics are documented for comparison. This helps validate cloud performance post-migration.

     

 


 

Choosing the right migration strategy and timeline

Not all Atlassian migrations follow the same path. Strategy selection depends on data size, complexity, and business constraints. A clear timeline aligns technical work with operational readiness.

  • Cloud-first versus hybrid transition decisions
    Organizations decide whether to move fully or run hybrid setups temporarily. This affects integration and access planning.

     
  • Phased or full migration approach selection
    Some teams migrate in phases to reduce risk. Others choose a single cutover to simplify coordination.

     
  • Downtime tolerance and scheduling analysis
    Acceptable downtime windows are defined early. This ensures business operations are not disrupted unexpectedly.

     
  • Stakeholder alignment and dependency mapping
    Dependencies between teams, tools, and processes are documented. This prevents delays during execution.

     
  • Migration roadmap and milestone definition
    Clear milestones track progress across preparation, testing, and execution. This keeps teams aligned and accountable.

     

 


 

Preparing Jira and Confluence data for migration

Data preparation is one of the most critical behind-the-scenes steps. Clean and structured data migrates more reliably to the cloud. Skipping preparation often causes errors and rework.

  • Data normalization and standardization efforts
    Field values, user names, and permissions are standardized. This avoids conflicts during import.

     
  • Archiving unused or obsolete content
    Old projects and spaces are archived or removed. This reduces clutter in the cloud environment.

     
  • User account and identity mapping
    Users are mapped to Atlassian accounts and email addresses. This ensures correct access after migration.

     
  • Permission and role validation
    Project and space permissions are reviewed carefully. Cloud permission models may differ from server setups.

     
  • Test exports to validate data structure
    Sample exports are created and reviewed. This confirms data readiness before full migration.

     

 


 

Executing migration using Atlassian-supported tools and methods

The actual migration relies on Atlassian-provided tools and structured execution steps. These tools handle data transfer while preserving relationships and history. Careful monitoring is essential throughout this phase.

  • Using Jira and Confluence cloud migration assistants
    Atlassian migration assistants guide data transfer. They validate compatibility and highlight potential issues.

     
  • Incremental versus full data transfer execution
    Teams may migrate data incrementally or in one run. The choice affects testing and downtime planning.

     
  • Monitoring logs and error reports during migration
    Migration logs are reviewed continuously. Early detection of errors prevents larger failures.

     
  • Handling large attachments and historical data
    Attachments and long histories require extra time. Proper handling ensures no data loss.

     
  • Maintaining source system stability during transfer
    The source environment is kept stable during migration. This avoids data inconsistency.

     

 


 

Testing cloud environment after migration completion

Testing confirms that the migrated environment works as expected. This step validates both technical accuracy and user experience. Skipping thorough testing increases post-migration issues.

  • Functional testing of projects and spaces
    Teams verify that issues, pages, and workflows function correctly. Core operations must work without errors.

     
  • Permission and access validation for users
    User access is tested across roles and teams. This ensures security and usability.

     
  • App and integration functionality checks
    Installed cloud apps and integrations are tested. Any gaps are addressed before go-live.

     
  • Performance and responsiveness evaluation
    Page load times and system responsiveness are reviewed. This confirms cloud performance benefits.

     
  • Issue and defect resolution before go-live
    Identified issues are resolved promptly. This stabilizes the environment for users.

     

 


 

Managing user readiness and change during transition

User readiness is a critical but often hidden part of migration. Even technically successful migrations can fail without proper user preparation. Clear communication reduces resistance and confusion.

  • Communication of migration timelines and impacts
    Users are informed about key dates and changes. This sets clear expectations.

     
  • Training on cloud-specific features and differences
    Cloud interfaces and features may differ from server versions. Training helps users adapt quickly.

     
  • Support planning for post-migration queries
    Support teams prepare for increased questions after go-live. This ensures faster issue resolution.

     
  • Documentation updates for new cloud processes
    Internal guides are updated to reflect cloud workflows. This supports long-term adoption.

     
  • Feedback collection and continuous improvement
    User feedback is gathered after migration. This helps refine configurations and processes.

     

 


 

Ensuring security, compliance, and long-term optimization

Cloud migration does not end at go-live. Ongoing security and optimization activities are required to maintain value. These steps ensure the environment remains secure and efficient.

  • Review of cloud security and access controls
    Security settings are reviewed against policies. This ensures data protection standards are met.

     
  • Compliance validation with organizational requirements
    Regulatory and internal compliance needs are verified. Audit readiness is maintained.

     
  • Monitoring usage and license optimization
    User activity and license usage are monitored. This helps control ongoing costs.

     
  • Performance tuning and configuration refinement
    Configurations are adjusted based on usage patterns. This improves efficiency over time.

     
  • Planning for future scalability and enhancements
    The cloud environment is reviewed for scalability. This supports future growth and changes.
