Legacy enterprise data warehouses (EDWs) are becoming a bottleneck for businesses aiming to scale operations and adopt advanced analytics. Traditional EDWs struggle with:
Migrating to a modern platform like Databricks offers elastic scalability, reduced costs, built-in security, and the ability to integrate open source technologies, avoiding vendor lock-in. This transformation empowers organizations to unlock real-time analytics and AI-driven decision-making while future-proofing their infrastructure.
Customers are also realizing these advantages of moving to the lakehouse. Check out this case study from Trek Bicycle!
Before Databricks, we had to run our retail analytics once a day on North American time, which meant our other regions got their data late. Now, we refresh the lakehouse three times per day, one for each region, and stakeholders receive fresh data in time to drive their decisions. Based on the results we’ve achieved in the lakehouse, we’re taking a Databricks-first approach to all our new projects. We’re even migrating many of our on premises BI solutions to Databricks because we’re all-in on the lakehouse.— Advait Raje, Team Lead, Data Engineering at Trek Bicycle
Migrating an EDW is complex, but doesn’t have to be risky. Databricks provides a structured five-step framework to ensure a smooth transition, which hundreds of customers have used.
Customers have been using this migration strategy to accelerate their migration projects. Check out this case study from VGZ!
Our new data platform was implemented seamlessly within three quarters: one for initial setup and golden source extraction, followed by a quarter dedicated to stabilization. This efficient rollout has brought us results that have exceeded our expectations and left us more than satisfied.— Rohan Horstman, Data Solutions Architect, VGZ
A comprehensive evaluation of your current environment lays the foundation for success. Key assessments include:
Designing the future state of your data warehouse involves aligning business goals with technical capabilities. This step includes defining key performance indicators (KPIs), too. Modernization choices include:
Selecting the right technology stack is critical—Databricks Lakehouse combines Delta Lake storage with distributed computing for scalability and interoperability.
Databricks supports two primary migration strategy approaches:
Using Databricks-native features like Lakehouse Federation ensures seamless transitions across both strategies.
Before scaling up migration efforts, validate assumptions and identify potential risks. Validation should include one of the following:
Clear success criteria ensure confidence in the migration process.
The final step involves full-scale implementation with continuous performance optimization and monitoring. Key focus areas include:
The last step with any migration is knowledge transfer. A successful migration extends beyond technical implementation to encompass organizational adoption and expertise development. Ensuring your teams can effectively utilize the Databricks Platform requires deliberate planning for knowledge acquisition and cultural adaptation to new workflows and capabilities.
Make sure you include skills development and change management, as well as thorough documentation and a knowledge base.
Databricks accelerates migrations with purpose-built features like Delta Lake’s unified storage format, automated ETL pipelines, and integrations with leading ISVs such as Fivetran and Tableau. These tools reduce complexity while enabling real-time analytics and AI-driven insights.
