Which Jira Cloud Migration Approach Is Right for Your Organization?

1. Introduction: Continuing the Migration Journey

In the first article of Jira DC to Jira Cloud migration series, the focus was on preparing the organization for Jira Cloud adoption-aligning teams, assessing environments, and establishing governance. This next step moves into execution: determining how the actual migration will occur.

No two Jira Data Center (DC) environments look alike. Some have remained close to Atlassian’s recommended configuration patterns, while others have evolved over years of workflow changes, custom scripts, Marketplace apps, and historical data accumulation. As a result, the path to Jira Cloud must reflect the structure, history, and complexity of the environment being moved.

This article examines the primary migration approaches available and how to determine which path aligns best with your environment.

2. Understanding the Jira DC to Jira Cloud Migration Landscape

A Jira DC instance typically carries a significant operational footprint, i.e., custom fields, marketplace apps, workflow schemes, post-functions, automation rules, and large volumes of historical issues. Jira Cloud, however, operates with standardized templates, modern API limits, and a different configuration architecture.

Because of these differences, no single migration approach fits every organization. Selecting the right approach must be grounded in technical realities rather than preference.

Key factors that influence the Jira DC to Jira Cloud migration include:

  • Jira DC version
  • Data volume and history retention requirements
  • Number and diversity of custom fields
  • Workflow and schema complexity
  • Marketplace app dependencies (whether their Cloud versions exist or support data migration)
  • Acceptable downtime window
  • Need for template transformation or data restructuring

Organizations with simple environments may find Cloud readiness straightforward; deeply customized instances require more nuanced approaches.

This article outlines the major migration approaches and how they apply to real-world DC-to-Cloud migration scenarios.

Migration Approach 1: Jira Cloud Migration Assistant (JCMA)

For many organizations, Atlassian’s native tool, Jira Cloud Migration Assistant (JCMA) represents the most straightforward migration path to Jira Cloud. Designed for environments that are already largely aligned with Cloud requirements, JCMA migrates projects, configurations, field templates, and users, providing a structured way to move metadata and content together.

JCMA works best when the on-prem environment already resembles Cloud conventions. However, it requires downtime. During this period, teams cannot work in Jira DC; any changes made during downtime would be lost unless repeated manually. JCMA does not support data transformations or data restructuring, meaning field templates and workflows must be Cloud-compatible before migration. App data migration depends entirely on whether the Cloud version of the app supports it.

When these requirements align-clean structure, compatible templates, and an acceptable downtime window, JCMA offers a predictable and fully supported migration path.

Migration Approach 2: CSV Export, Manual Migration, or Custom Scripting

CSV-based or scripted migrations provide flexibility but come with significant limitations. They are best suited for highly targeted transfers, such as moving a small subset of issues, migrating only a few isolated projects, or transitioning from a limited team to Cloud ahead of others. In other words, they are appropriate for scenarios where the volume of data is intentionally small, and the scope is deliberately narrow.

However, this approach also demands caution. CSV exports do not preserve comments, attachments, issue history, or links. Organizations must expect manual cleanup and reconfiguration. Like JCMA, a downtime window is unavoidable, because issues exported at different times quickly fall out of sync with the source system. The risk of human error is also materially higher.

Although not suited for large or mission-critical environments, CSV and scripting can serve as useful migration approaches for controlled, low-volume data migration.

Migration Approach 3: Hybrid Migration Using JCMA + OpsHub Migration Manager

A hybrid migration approach combines the strengths of JCMA and OpsHub Migration Manager (OMM), an enterprise data migration platform from Atlassian Solutions Partner, OpsHub to support environments that are structurally aligned with Jira Cloud but require flexibility beyond what JCMA alone offers. In this model, JCMA performs the initial load, and OMM is layered on top to manage incremental changes.

JCMA handles the first, structured phase of migration-moving projects, workflows, field templates, schemas, and meta data. Once JCMA completes the foundational migration, OMM then synchronizes the ongoing updates and manages the elements that require higher adaptability, such as field mismatches or required data-level transformation.

During this hybrid migration, Jira Data Center and Jira Cloud operate in parallel, with OMM continuously syncing incremental changes. This significantly reduces downtime, as teams can continue working in DC while Cloud is validated and gradually brought into alignment.

Hybrid migration is most effective when the configuration templates are compatible with JCMA, but the organization requires ongoing synchronization, no downtime, or controlled transformation at the data level.

Migration Approach 4: Enterprise – Grade Migration Platforms

Some Jira Data Center environments are simply too complex, too large, or too business-critical for downtime or manual remediation. These are instances with deep customizations, thousands of users, large historical datasets, or multi-system dependencies.

In such scenarios, teams often look to enterprise migration platforms, such as OpsHub Migration Manager (OMM), which are designed to support zero downtime, phased execution, parallel use of Data Center and Cloud, data transformation during migration,

OMM preserving issue history, comments, attachments, links, transitions, relationships, etc. - without zero downtime. It also supports template transformation, works with older Jira versions, and offers reconciliation and validation to ensure Cloud matches Data Center.

For highly customized environments or organizations needing continuous operations during migration, enterprise-class migration tools like OMM are often the safest and most suitable choice.

Factors That Help Determine the Right Migration Approach

Choosing the right Jira Cloud migration approach requires evaluating the following five key factors that directly influence data fidelity, operational continuity, and risk tolerance:

Data Richness

  • How rich is the data today, and how much must be preserved? Loss of richness (rich text, comments, relationships, attachments, embedded images, references) can create significant operational impact.

Need for Data Transformation

  • Does migration require cleanup or rationalization?
  • Common needs include template standardization, field consolidation, data masking, status cleanup, and project/team restructuring.

Downtime Tolerance

  • How much downtime can teams accept during migration?
  • Downtime-planned or unplanned, can disrupt global teams and increase total migration costs.

Aggregate Data Needs

  • Will teams need unified reporting while migration waves are in progress?
  • Wave-based moves can temporarily split data across systems, affecting compliance, capitalization, financial reporting, and portfolio visibility.

Recovery and Mitigation

  • What mechanisms are needed to recover from failures?
  • Large-scale migrations face endpoint failures, mapping issues, inconsistent data, and system defects; resilience must be built in.

Practical Scenarios

To illustrate how these approaches apply in real environments:

  • A standardized DC instance with acceptable downtime typically aligns with JCMA.
  • A workflow-heavy instance with mismatched templates and retained history requirements often benefit from the hybrid model.
  • A highly customized instance with continuous operations generally requires an enterprise-grade platform
  • A very small dataset or a limited team may be suitable for CSV or scripting.

Post-Migration Stabilization

After migrating to Cloud, stabilization becomes essential. Organizations must validate data integrity-issue history, links, attachments, and permissions-confirm workflow behavior, review access controls, monitor Cloud performance, and gather team feedback. Cloud environments also benefit from post-migration configuration refinements as teams adjust to new capabilities.

Conclusion

There is no single Jira Cloud migration approach that fits every organization. JCMA works well for standardized environments willing to accommodate downtime. CSV and scripting serve very narrow and low-volume use cases. Hybrid approaches reduce downtime while preserving higher data fidelity. Enterprise data migration platforms provide the highest degree of continuity and accuracy for complex or regulated environments.

When the chosen strategy reflects the true structure and operational realities of the Jira DC environment, the Cloud migration becomes far more predictable, controlled, and ultimately successful.
