We migrate data for companies in Barcelona from legacy systems, on-premise servers and obsolete data warehouses to modern cloud platforms like Snowflake and Databricks, with detailed migration plans, exhaustive integrity validation and zero data loss. We reduce infrastructure costs and leave your data platform ready to scale with artificial intelligence.
Cloud Data Migration with Snowflake and Databricks in Barcelona
At MiT Software we specialize in migrating data infrastructures to Snowflake and Databricks, the two most widely adopted cloud data platforms by leading companies worldwide. Our migration methodology guarantees complete data integrity, business continuity throughout the process and a controlled transition that minimizes operational risk. We migrate from any source: Oracle, SQL Server, Teradata, on-premise Hadoop, Amazon Redshift, Google BigQuery, SAP BW or any existing data warehouse or data lake. The result is a modern, scalable data platform with significantly superior analytical performance and optimized infrastructure costs compared to the previous system.
We start with a detailed inventory of your Barcelona company's source system: tables and volumes, dependencies between components, existing pipelines, connected applications and business criticality of each component. This inventory is the basis of the migration plan, which defines the order, phases and success criteria for each migrated element.
We define the complete architecture in the target platform for your Barcelona company: database and schema organization, role and permissions model, warehouse or cluster configuration, network security, connectivity with existing systems and integration with the BI and ML tools that will consume the migrated data.
We develop the complete migration tooling for your Barcelona project: ETL/ELT extraction and loading scripts, SQL conversion tools for dialect adaptation, validation scripts for integrity testing and orchestration pipelines that automate and monitor the entire migration process from end to end.
We execute migration progressively and in a controlled manner, starting with the least critical components of your Barcelona company's system and gradually moving to the most important ones. Each phase includes exhaustive validation before proceeding to the next, ensuring no stage advances until confirming the quality and integrity of the already migrated data.
We execute the final cutover with minimum maintenance window for Barcelona companies, redirecting all applications and users to the new platform in a coordinated manner. During the first days after cutover we provide intensive support to detect and resolve any incident that may arise in the new production environment.
Once the new platform is stabilized and validated, we coordinate the controlled decommissioning of your Barcelona company's legacy system and perform a post-migration optimization review that identifies additional opportunities to reduce costs and improve performance in the new cloud environment.
The on-premise data warehouses still operating at many Barcelona companies generate high fixed costs regardless of actual usage. Migrating to Snowflake or Databricks eliminates those fixed costs, replaces them with a pay-per-use model and provides virtually unlimited scalability without needing to plan capacity months in advance.
Cloud-native platforms like Snowflake and Databricks are designed for enterprise-scale analytical workloads. Barcelona companies that migrate to these platforms experience very significant performance improvements: queries that took hours in the legacy system complete in seconds, unlocking analyses that were previously unfeasible due to technical limitations.
Snowflake is the reference platform for Barcelona companies seeking a high-performance, secure and easy-to-operate cloud data warehouse. We manage the complete migration from any source system: schema conversion, data migration, adaptation of existing pipelines, security configuration and team training for autonomous operation.
Databricks is the ideal option for Barcelona companies that need to combine large-scale data analytics with machine learning and artificial intelligence. We manage the migration of data warehouses, data lakes and ML pipelines to Databricks, implementing the Lakehouse architecture that unifies analytics and AI on a single platform.
We have specialized experience migrating from the most common enterprise data warehouse systems in Barcelona to Snowflake or Databricks: SQL dialect conversion, stored procedure migration, view and function adaptation, and performance optimization of migrated queries to leverage the cloud architecture.
Many Barcelona companies that adopted Hadoop in the first Big Data wave now face the challenge of modernizing that aging infrastructure. We migrate complete Hadoop ecosystems — HDFS, Hive, Spark, HBase — to cloud equivalents in Snowflake or Databricks, preserving existing processing logic and eliminating the operational burden of the on-premise cluster.
Every migration we execute for companies in Barcelona includes a rigorous integrity validation process: record counting at each stage, checksum comparison, statistical validations of key metrics and functional testing of the main queries and reports. No phase advances until confirming that the migrated data is complete and correct.
Migration is the ideal opportunity to optimize your Barcelona company's data model: normalize or denormalize schemas according to the access patterns of the new platform, eliminate redundancies accumulated over years, improve partitioning strategies and adapt the physical design to maximize analytical performance in Snowflake or Databricks.
