Exchange to Gmail Migration Challenges and EdbMails Solutions
Challenge 1: IMAP Connection Limits or Throttling during Bulk Migration
EdbMails automatically manages throttling limits using smart reconnection logic. If a session gets throttled or disconnected, the software pauses and reconnects to continue the migration without user intervention. This ensures uninterrupted transfer even for large-scale or multi-mailbox migrations, maintaining migration continuity and stability.
Challenge 2: Maintaining Folder Hierarchy and Integrity
EdbMails preserves folder hierarchy, message properties, and metadata such as read/unread status, timestamps, and attachments during Exchange to Gmail migration. It accurately maps the Exchange folder structure as nested folders in Gmail, ensuring users find their data organized just as it was before migration.
