Welcome to Bridger
Plan, document, and manage data migration mappings with confidence.
Bridger is a professional data migration planning tool designed to help teams document, track, and manage field mappings between legacy and modern database systems. Whether you're converting a decades-old system or integrating new platforms, Bridger provides the structure and tools to make complex migrations manageable.
At its core, Bridger helps you answer three critical questions:
- What data exists in the source system?
- Where does it need to go in the target system?
- How will it be transformed along the way?
