LEGACY DATA MODERNIZATION & CLOUD MIGRATION

Data Platform Modernization, Legacy Warehouse Deprecation & Cloud Migration

Migrating legacy on-premise relational databases, Hadoop clusters, and legacy data warehouses to scalable, high-performance cloud lakehouses on Azure, AWS, and GCP.

STRATEGIC PERSPECTIVE

The Data Modernization Mandate: Escaping Legacy Architecture Bottlenecks

Strategic Imperative: Legacy on-premise data warehouses and aging Hadoop clusters trap enterprise data in expensive, siloed hardware that cannot support modern AI workloads.

For decades, global enterprises relied on legacy data warehouses such as Teradata, Oracle Exadata, and Netezza, or complex on-premise Hadoop/Cloudera clusters to store and process corporate analytics. Today, these monolithic architectures represent major operational bottlenecks: their rigid compute-storage coupling leads to exorbitant expansion licensing costs, nocturnal batch processing failures, and an inability to power modern machine learning workloads.

Routeget’s Data Platform Modernization practice provides strategic architectural guidance and hands-on migration execution to transition mission-critical data estates to modern cloud lakehouses. We decouple compute from storage, automate code translation (SQL, PL/SQL, MapReduce, Spark), and migrate multi-terabyte data stores with zero disruption to daily enterprise operations.

Our modernization methodology goes beyond simple lift-and-shift migration. We re-architect enterprise data architectures into agile Medallion (Bronze/Silver/Gold) cloud lakehouse topologies on platforms like Microsoft Fabric, Snowflake, and Databricks. We implement unified data governance, automate pipeline monitoring, and reduce annual data infrastructure operational costs by up to 50%.

EXECUTIVE FAQ

Frequently Asked Questions: Data Modernization

Insights into Routeget’s modernization methodologies, risk mitigation protocols, and cloud platforms.

How does Routeget prevent business disruption during the migration process?

We utilize an automated dual-run methodology where legacy and cloud platforms operate in parallel. Continuous Change Data Capture (CDC) replication keeps both systems synchronized, allowing thorough user acceptance testing and report reconciliation before any production cutover occurs.

Can our existing SQL queries and BI dashboards be preserved?

Yes. Our automated code translation engines refactor legacy SQL dialects and stored procedures into ANSI-compliant cloud SQL or native equivalents. In most cases, existing Power BI and Tableau dashboards require only connection string updates to point to the new cloud lakehouse.

What is the typical timeline for an enterprise data warehouse modernization?

While timelines depend on estate complexity and data volume, a typical enterprise migration spanning 5 to 20 terabytes of data and hundreds of ETL workflows is completed in 3 to 6 months using our phased wave methodology.

How is data security maintained during transit and cloud storage?

All data migrated to the cloud is encrypted in transit using TLS 1.3 and at rest using customer-managed encryption keys (CMEK) via cloud key vaults. Routeget adheres to strict zero-trust network architectures throughout the migration lifecycle.
