PST/OST and IMAP Mailbox Migration

The Cigati Email Migration Tool allows users to migrate mailbox data from PST/OST files and IMAP-enabled email accounts with complete accuracy. It supports both local Outlook data files and live IMAP mailboxes, making it suitable for different migration requirements. Throughout the migration process, the software preserves the original folder hierarchy, email properties, attachments, contacts, calendars, and other mailbox items without altering the source data.

bulk-file

Single and Bulk Mailbox Migration

The software supports both single and bulk migration modes to simplify mailbox transfer projects of every size. Users can migrate an individual PST/OST file with mailbox preview or process multiple PST/OST files simultaneously. For IMAP migration, administrators can upload multiple accounts using a CSV file, allowing large-scale mailbox migration with minimal manual effort and improved productivity.

preview

Mailbox Preview Before Migration

The Cigati Email Migration Tool includes a built-in Mailbox Preview feature that helps users verify mailbox data before migration. In PST/OST Migration, the preview is available only when a single PST or OST file is selected, allowing users to examine mailbox folders and email content before proceeding. In IMAP Migration, users can browse the mailbox structure, view available folders, and select the required mailboxes for migration after establishing a successful IMAP connection. This feature helps ensure accurate mailbox selection, minimizes unwanted data transfer, and preserves the original folder hierarchy throughout the migration process.

filter

Selective Migration with Advanced Filters

The software includes advanced filtering options that help users migrate only the required mailbox data. Users can apply a Date Range Filter, choose specific mailbox folders, and migrate only selected data. During PST/OST migration, an Item Type Filter is also available to migrate only emails, contacts, calendars, or tasks, making the migration process more flexible and efficient.

duplicates

Intelligent Duplicate Handling

The Cigati Email Migration Tool includes a smart duplicate detection feature that compares mailbox items using properties such as Subject, Sender, Recipient, CC, and Body. Duplicate emails are automatically skipped during migration, helping users maintain a clean destination mailbox while reducing unnecessary storage usage and migration time.

skip

Skip Previously Migrated Emails

The software can identify mailbox items that have already been migrated during earlier sessions. Instead of transferring the same emails repeatedly, it skips previously migrated items and processes only new mailbox data. This incremental migration capability improves efficiency and prevents duplicate mailbox entries.

contact

Export Contacts and Calendars Separately

During PST/OST migration, the software allows users to export Contacts in VCF (.vcf) format and Calendars in ICS (.ics) format. These industry-standard formats ensure compatibility with various email clients and contact management applications while providing additional flexibility for backup and data sharing.

strip-pdf-splitter-tool

Split PST and PDF Size Management

The tool includes advanced output management options for PST and PDF files. Users can split large PST files into smaller, manageable sizes to improve Outlook performance and simplify storage. When exporting mailbox data to PDF, the software also provides a PDF Size Restriction option that helps generate organized and easily manageable PDF documents.

data

Custom Folder Name and Organized Migration

Users can assign custom folder names before starting the migration process. This feature helps organize migrated mailbox data efficiently within the destination location, making it easier to identify, manage, and access migrated folders after the migration is complete.

free

Free Up Server Space

For IMAP migration, the software provides an option to remove successfully migrated emails from the source mailbox after verification. This helps organizations free up server storage, improve mailbox management, and optimize email server performance without affecting the migrated data.
