A well-planned migration allows businesses to modernize analytics, unify data, and prepare for advanced data-driven initiatives. Poor planning can lead to data loss , downtime, or wasted resources, undermining confidence in the platform.
1. Assess Current Systems and Data Landscape Start by comprehensively evaluating existing infrastructure, including data warehouses , ETL pipelines, reporting systems, and databases. Document data dependencies, workflows, and quality issues that will need to be addressed during migration. Identify critical datasets and categorize them by type (structured, semi-structured, or unstructured).
Databricks provides automated discovery tools that can profile your existing workloads and estimate migration complexity. Use these tools to understand the scope of your migration and identify potential challenges early. This assessment lays the foundation for a smooth migration by providing visibility into what needs to be moved and how it’s currently being used.
2. Define Objectives and Success Metrics Clearly define the goals of migration beyond just “moving to the cloud .” Objectives might include improving data accessibility by enabling self-service analytics, supporting advanced analytics and ML initiatives, or enabling real-time reporting for operational decisions. Establish measurable KPIs, such as time to refresh data, query latency, error rates, or cost reduction, to demonstrate progress.
These metrics help track the success of migration and measure return on investment throughout the process. They also provide objective criteria for evaluating whether the migration is meeting business needs. Share these metrics with stakeholders regularly to maintain visibility and support for the initiative.
3. Plan a Phased Migration Strategy Avoid migrating all workloads at once, which creates unnecessary risk and complexity. Begin with low-risk or non-critical datasets such as historical or archive data that are less time-sensitive. Use early migration phases as proof-of-concept to validate data integrity , test pipelines, and optimize performance before moving critical workloads.
Databricks supports two primary migration approaches: ETL-first (back-to-front), which builds a solid data foundation before migrating dashboards, and BI-first (front-to-back), which replicates dashboards first to showcase immediate business value. Choose the approach that aligns with your organizational priorities and stakeholder needs.
Gradual migration minimizes disruption and builds confidence in the new platform through demonstrated success. Each phase should deliver tangible value and incorporate lessons learned from previous phases.
4. Ensure Data Quality and Governance Legacy systems often contain inconsistent or incomplete data accumulated over years of operation. Standardize formats, clean duplicates, and validate datasets before migration to avoid carrying forward quality issues. Establish governance policies using Unity Catalog to maintain data integrity and compliance in the new environment.
Implement data quality checks in your migration pipelines rather than assuming data is clean. Delta Lake’s schema enforcement helps prevent insufficient data from entering your lakehouse, but source data quality still matters. Hence, a clean, well-governed data environment ensures reliable analytics after migration and builds trust in the new platform.
5. Address Dependencies and Workflow Refactoring Legacy systems may support multiple downstream applications and reporting tools that depend on specific data formats, schemas, or availability schedules. Map all dependencies thoroughly, refactor workflows as needed, and verify integrations before migrating production workloads. Consider using Databricks Lakehouse Federation to query legacy systems during the transition period.
Running old and new systems in parallel for a period can help ensure a smooth transition and validate that migrated data produces the same results. This parallel operation provides a safety net and builds confidence before fully decommissioning legacy systems.
6. Prepare Change Management and Training Migration affects people and processes as much as technology. Provide training and documentation for data teams and business users that address their specific roles and needs. Communicate the benefits of the new platform clearly and assign roles for data ownership and governance that establish accountability.
Effective change management ensures user adoption and maximizes the value of Databricks. Create internal champions who understand the platform well and can help their colleagues. Provide hands-on training rather than just presentations. Show users how the new platform solves their specific problems better than legacy systems.
7. Validate and Monitor Post-Migration After migration, run extensive validation to ensure data completeness and accuracy by comparing outputs with legacy systems to confirm results. Implement monitoring and observability for pipelines, jobs, and data quality to maintain stable operations and prevent issues from impacting business users.
Databricks provides built-in monitoring capabilities and integrates with tools like Monte Carlo and Bigeye for data observability . Set up alerts for pipeline failures, data quality issues, and performance degradation to quickly identify and resolve problems.
8. Decommission Legacy Systems Once validation is complete and teams have successfully adopted Databricks, systematically phase out legacy infrastructure. Decommissioning reduces maintenance costs, eliminates redundancies, and ensures resources are fully focused on the modern platform. Keep legacy systems in read-only mode initially in case reference access is needed, then fully decommission once confidence is established.
Document what was retired, when, and why to maintain institutional knowledge. Celebrate the decommissioning milestone with stakeholders to reinforce the success of the migration.
