Legacy Database Schemas
Were Not Built for the Cloud
Enterprise data migration programs routinely stall at the schema layer. Legacy database designs were built for on-premise systems, and when migrated to cloud platforms without redesign, they retain structural inefficiencies and design constraints that limit performance and drive up compute costs.
NuSummit’s The Architect analyzes legacy DDL structures, data types, and platform constructs, then generates target-native schema designs for Databricks, Microsoft Fabric, Snowflake, BigQuery, and AWS, reducing manual conversion effort, surfacing compatibility issues before data moves, and keeping architects in control through a governed review-and-approval workflow.
What We Deliver
Schema and DDL Conversion
Transforms source DDL, schema structures, and database objects into cloud-ready definitions for the chosen target platform.
Data Type and Object Modernization
Optimizes data types, object definitions, and partitioning strategies so that schemas are redesigned for cloud performance rather than replicated from legacy systems.
Target-Aware Platform Optimization
Applies platform-specific best practices for Databricks, Microsoft Fabric, Snowflake, BigQuery, and AWS to improve schema performance, scalability, and maintainability.
Schema Mapping and Impact Analysis
Generates source-to-target mappings and documents conversion considerations, compatibility gaps, and downstream impacts before data migration begins.
Human-in-the-Loop Validation
Generated schemas can be reviewed, refined, and approved by enterprise architects before moving into deployment workflows.
Reusable
Modernization Rules
Supports rule libraries and modernization playbooks that standardize conversion decisions across multiple source systems and target platforms.
Architect Review Workflow
Structures the review process so that architecture teams focus on exceptions and approvals rather than repetitive manual conversion tasks.
Enterprise Ecosystem Integration
Supports cloud migration factories, governance workflows, and the broader NuSummit agent ecosystem for end-to-end data modernization.
The NuSummit Advantage
Use Cases
Migration Readiness Starts at the Schema Layer
Schema modernization is where migration programs slow down or stall. Legacy structures built for on-premises systems do not perform well in cloud environments, and manual conversion introduces errors, inconsistencies, and delays that compound across large programs.
The Architect addresses this by automating schema analysis, DDL conversion, target-platform optimization, and impact mapping, while keeping enterprise architects in control of every validation and approval decision. Migration readiness comes faster, with fewer conversion risks, and with governance built in from the start.
