When switching between two IMAP email accounts, one of the biggest concerns is whether attachments, folder structure, and email properties will remain intact after migration. Native migration methods often require configuring both accounts manually and monitoring the process for errors. For larger mailboxes, this can become difficult to manage. SysInfo IMAP Backup Tool provides a direct IMAP-to-IMAP migration option that securely transfers mailbox data between supported IMAP accounts. The software migrates emails along with their attachments while preserving the original folder hierarchy throughout the process. Before starting, users can preview mailbox folders, choose specific data for migration, and apply date-based filters to transfer only the required emails. It also includes duplicate email removal, the option to skip previously migrated items, and flexible attachment management, allowing attachments to be migrated normally, excluded, or saved separately if required. Organizations handling multiple email accounts can also use Batch Mode by importing account details through a CSV file. With support for Gmail, Office 365, Google Workspace, and other IMAP services, the tool simplifies mailbox migration while helping maintain data consistency from source to destination.
