Map your migration.
Move with confidence.
Bridger is the professional desktop tool for planning, documenting, and validating complex database-to-database migrations — from schema import to final validation script.
Schema Import
Load source and target schemas from CSV, DDL, JSON, or spreadsheet. Bridger normalizes everything into a unified model.
Mapping Management
Define column-level mappings with transformation logic, status indicators, notations, and source group associations.
AI-Assisted Mapping
Use local LLM inference via Ollama to generate and review column mappings, reducing manual effort on large schemas.
Validation Scripts
Generate dialect-aware SQL validation queries from your mappings and run them directly against the converted database.
Built for the realities of migration work
Real migrations are messy. Source systems have undocumented tables, inconsistent types, and decades of accumulated conventions. Bridger gives you a structured workspace to capture that complexity — not a form that assumes everything is clean.
One tool for the whole planning cycle
Reusable mapping patterns
Store common transformation logic in a shared library and push updates across every project that references them. Keep your team aligned on standards.
Model source complexity
Many-to-one source relationships — multiple legacy tables feeding a single target — are first-class citizens in Bridger's data model.
Deliverables built in
Generate Excel and formatted reports directly from your mapping workbook. Clients and stakeholders get a clear picture without any extra work.
