Choosing Your Strategy
Technical Considerations
Key technical aspects to understand for your migration:
- Folder hierarchy preservation - The platform recreates exact folder structures in the target
- Multiple migration passes - Delta passes ensure new content is captured
- Selective migration - Migrate recent emails (e.g., last 6 months) while deferring older content
- Throttling optimization - Continuous optimization of API calls maximizes throughput
