Data Center to Cloud: Your Step-by-Step Migration Roadmap
Moving from Atlassian Data Center to Atlassian Cloud is a significant decision for any organization. The shift affects security, performance, collaboration, and long-term reliability. Because these systems support core business operations, the migration process must follow a structured plan that accounts for technical, administrative, and organizational needs.
This step-by-step roadmap outlines how to approach the migration with precision and predictability. It explains each stage, why it matters, what to watch for, and how a guided method helps your teams transition with confidence.
1. Why a Roadmap Is Essential
Data Center environments evolve over many years. They gather custom fields, workflows, plugins, integrations, archived items, and user structures. Without a roadmap, migration becomes uncertain. Teams risk incomplete transfers, permission issues, or inconsistent behavior in the new environment.
A roadmap creates order. It defines each step, sets expectations, assigns ownership, and reduces uncertainty. It also helps business stakeholders understand timelines, dependencies, and required approvals.
2. Stage One: Discovery
Discovery is the foundation. It establishes a factual picture of your current environment. Teams collect detailed information about:
- Users and groups
- Permission schemes
- Custom fields
- Workflows
- Automation rules
- Integrations
- Marketplace apps
- Project or space volume
- Data sensitivity
- Infrastructure dependencies
- Regulatory requirements
What Makes Discovery Important Without accurate discovery, teams underestimate complexity. Apps may behave differently. Workflows may contain outdated rules. Custom fields may be unused but still mapped. Discovery avoids these gaps by gathering objective data before planning begins.
3. Stage Two: Assessment
Assessment interprets the discovery details. It answers key questions:
- Which items should migrate?
- Which items should be archived?
- Which apps have Cloud equivalents?
- Which apps require alternatives?
- What needs reconfiguration before migration?
- What risks exist?
- What dependencies could affect timing?
Assessment also reviews security and compliance expectations, including data residency, access control, and audit requirements.
Why Assessment Matters Assessment identifies mismatches early. For example:
- Some apps cannot migrate directly.
- Certain integrations require rewriting.
- Permissions may not align with Cloud models.
- Workflows may contain elements that behave differently.
By identifying these issues upfront, teams avoid disruption later.
4. Stage Three: Cleanup
Cleanup is one of the most impactful phases in the roadmap. It removes unnecessary items, simplifies structures, and reduces data load. Cleanup may include:
- Deleting inactive users
- Archiving old projects or spaces
- Removing unused fields
- Consolidating redundant workflows
- Reviewing automation rules
- Evaluating app usage
- Standardizing naming conventions
- Reducing duplicate schemes
Why Cleanup Matters A cleaner environment reduces migration time, simplifies testing, and improves Cloud performance. It also lowers long-term administration costs. Cleanup ensures that only relevant, active components move forward.
5. Stage Four: Planning
Planning converts discovery and assessment into a detailed migration plan. This plan includes:
- Timelines
- Milestones
- Responsibilities
- App pathway decisions
- Integration mapping
- User provisioning rules
- Security and compliance requirements
- Communication sequences
- Expected downtime windows
- Training needs
- Testing cycles
Why Planning Matters Clear planning minimizes confusion. It also helps procurement, security, and leadership prepare for licensing changes, infrastructure updates, and budget cycles. Without planning, unexpected delays are common.
6. Stage Five: Test Migration
Testing is a controlled rehearsal of the final migration. It exposes gaps, errors, and unexpected outcomes before the production move. Test migration validates:
- Workflow behavior
- Custom field mapping
- User access
- Permission alignment
- Automation rules
- App functionality
- Integration behavior
- Performance in Cloud
- Data completeness
Why Testing Matters Testing ensures reliability. If issues appear, teams adjust workflows, permissions, fields, or scripts. Testing reduces risk and builds confidence for the final cutover.
7. Stage Six: User Preparation
Before the final move, users need clear communication and guidance. This stage includes:
- Sharing timelines
- Explaining expected downtime
- Providing Cloud onboarding materials
- Highlighting interface differences
- Conducting training sessions
- Updating team leads
- Preparing FAQs
Why User Preparation Matters Even a well-executed migration can cause confusion if users are not informed. Proper communication ensures smoother adoption and fewer support requests.
8. Stage Seven: Final Cutover
The final migration happens once testing confirms readiness. Cutover includes:
- Freezing the Data Center environment
- Performing final data sync
- Running the migration tool
- Verifying successful transfer
- Activating users in Cloud
- Reconnecting apps or integrations
- Validating permissions
- Opening support channels
Why Cutover Matters A structured cutover minimizes downtime and avoids misalignment between users and data. When handled properly, systems remain stable and predictable as teams begin using the Cloud environment.
9. Stage Eight: Post-Migration Optimization
After the migration, optimization ensures the Cloud setup functions at its best. This may include:
- Updating dashboards
- Refining automation
- Rebuilding or enhancing reports
- Adjusting project templates
- Improving permission grouping
- Reviewing performance
- Completing final app configurations
- Gathering user feedback
Why Optimization Matters Migration alone is not the end. Optimization ensures that workflows, data, and user interfaces fully support long-term needs. It allows teams to take advantage of Cloud capabilities with minimal friction.
10. The Importance of App Pathway Planning
Apps often shape the success of a migration. Many organizations depend heavily on Marketplace apps for automation, reporting, integration, or advanced workflows. But apps differ between Data Center and Cloud. Some features may be missing or redesigned.
Key steps in app planning include:
- Identifying Cloud equivalents
- Confirming vendor support
- Reviewing pricing differences
- Testing app behavior
- Checking data transfer compatibility
- Finding alternatives if needed
Proper planning avoids unexpected gaps that can affect critical workflows.
11. Security and Compliance in the Roadmap
Security and compliance cannot be treated as an afterthought. Cloud environments have different controls, permissions, and audit processes. The roadmap incorporates:
- Access control mapping
- Data residency selection
- Encryption standards
- Logging and monitoring differences
- Regulatory requirements for specific industries
- Internal audit validation
These checks ensure the Cloud environment aligns with organizational obligations.
12. Collaboration Across Teams
Migration is not an IT-only project. It requires cooperation across:
- IT leadership
- Platform administrators
- Compliance teams
- Security teams
- Procurement
- Project managers
- Business units
The roadmap helps coordinate these teams with clear responsibilities and timelines.
