This comprehensive guide explores the different Atlassian migration strategies, methodologies, and best practices to ensure your transition delivers maximum business value with minimal disruption.

Understanding Atlassian Cloud Migration Approaches

Selecting the right migration strategy is important for a successful transition to Atlassian Cloud. Each approach offers distinct advantages based on your organization's size, complexity, and business requirements.

Lift and Shift Migration: The Comprehensive Approach

The Lift and Shift migration strategy involves moving your entire Atlassian environment to the cloud in a single, coordinated effort. This approach transfers all data, users, and configurations during one planned downtime window, maintaining your current setup with minimal changes.

When to use this approach:

  • Organizations with fewer than 10,000 users
  • Teams needing to migrate quickly without extensive reconfiguration
  • Businesses wanting to retain all historical data and workflows
  • Companies looking to minimize operational disruptions during transition

The Lift and Shift method is Atlassian's recommended approach for most organizations, particularly those with less than 10,000 users. This strategy offers several key benefits:

  • Faster transition to cloud by moving all components simultaneously
  • Complete data preservation, ensuring continuity for users familiar with existing processes
  • Simplified migration process without extensive redesigns or data audits
  • Immediate access to Atlassian Cloud features from day one

However, this approach requires careful planning to address potential challenges such as extended downtime if issues arise, migration of unnecessary legacy data, and limited opportunities to optimize workflows during transition.

Phased Migration: The Incremental Approach

The Phased Migration strategy breaks down the migration process into manageable stages, allowing you to migrate data and users incrementally. This approach is typically implemented by transitioning individual departments, business units, or smaller teams in sequence.

When to use this approach:

  • Organizations with over 10,000 users
  • Enterprises with complex environments or multiple instances
  • Businesses that must minimize downtime by migrating in stages
  • Companies needing to test cloud performance with smaller groups before full rollout

Phased Migration offers distinct advantages for larger or more complex organizations:

  • Reduced downtime by maintaining operational continuity during transition
  • Incremental testing opportunities to identify and resolve issues before proceeding
  • Strategic flexibility to adapt based on feedback from earlier phases
  • Gradual change management to help teams adjust to new systems and processes

The primary challenges with this approach include more complex coordination across phases, potential inconsistencies between cloud and on-premises environments during transition, and extended migration timelines that may delay full ROI realization.

Fresh Start Migration: The Clean Slate Approach

The Fresh Start migration strategy involves setting up a new cloud instance and selectively migrating only essential users and workflows, leaving behind existing data on the old instance. This approach allows you to optimize your cloud environment without the burden of unnecessary historical data.

When to use this approach:

  • Organizations looking to streamline operations and eliminate obsolete data
  • Teams wanting to redefine workflows and processes in the cloud
  • Businesses with current instances cluttered with redundant data
  • Companies setting up new teams or projects that require a clean slate

The Fresh Start method provides unique benefits:

  • Streamlined environment with reduced clutter by migrating only essential data
  • Optimized workflows tailored to current business needs
  • Reduced migration complexity by focusing on necessary components
  • Faster implementation with less data to transfer compared to other approaches

Organizations choosing this path should be aware of potential data loss risks without careful assessment, change management challenges as employees adapt to new workflows, and the initial resource requirements for thorough planning and configuration setup.

Key Migration Planning Considerations

Regardless of which migration strategy you select, several critical factors must be addressed to ensure a successful transition to Atlassian Cloud.

Data Assessment and Cleanup

Before migration, conducting a comprehensive audit of your existing environment is essential. This process should:
