# Migration source connectors
Migration source connectors are DLL libraries that enable Epona.Migrate to import documents from external systems. Each connector implements source-specific logic for authentication, document retrieval, metadata extraction, and transfer to SharePoint.
# What is a migration connector
A migration connector is a .NET library that:
- Connects to a specific document source system (e.g., Box, iManage)
- Authenticates using provided credentials
- Enumerates documents and folders
- Extracts metadata (date, owner, custom fields)
- Streams document content to SharePoint
- Logs progress and errors
Connectors are auto-discovered by the migration engine when placed in the same directory as Epona.Migrate.exe.

- Provide source system credentials and connection details in Epona.Migrate configuration
- The migration engine auto-discovers and loads the connector
# Configuration pattern
All migration connectors require:
- Connection settings — API credentials, endpoints, authentication method
- Source location — starting folder, workspace, or container to scan
- Metadata mapping — source fields → SharePoint columns
- Matter/client matching — how to map source documents to SharePoint structure
- Filtering — optional rules to exclude certain documents or folders
