SysTools
IMAP Migration Tool

Universal IMAP Support

Easily migrate emails to and from any IMAP-enabled server. SysTools IMAP Migration tool offers built-in support for all popular domains like Gmail, Yahoo, iCloud, etc. plus the option to choose your custom domain too. Ensure a smooth connection everytime.

Bulk IMAP Migration

This software to migrate IMAP accounts allows you to add multiple user accounts in a single migration run with the help of a CSV template. Save countless hours and reduce total migration time by transferring emails between many IMAP accounts at once.

Maintain Data Integrity

SysTools IMAP Migrator guarantees a perfect email transfer everytime. It preserves the original folder hierarchy, email metadata (including the read/unread status), and all other message properties. Use it to ensure that the IMAP Account data arrives in the destination exactly like it was in the source.

Smart Delta Migration

Avoid email data duplication and speed up subsequent IMAP transfers with the help of the dedicated Delta Migration option. Available at the end of your first run, this feature syncs only the newly received mails, skipping over all the items that have already been moved. Perfect for phased IMAP migrations.

Realtime IMAP Migration Monitoring

Stay informed at all times with a live Dashboard that tracks every single email in all IMAP accounts. Find users instantly with the help of the search bar, or switch tabs to witness accounts under specific status:

• In-progress: Contains accounts currently being migrated.
• Pending: Shows user accounts waiting in queue for migration.
• Completed: Displays all accounts which have finished IMAP mail transfer.

Flexible Rerun and Error Handling

Migrate IMAP accounts with confidence and move emails with complete control. This tool provides its users multiple modes to handle any scenario with ease, so manage the process even if your initial run is not up to mark.

• Retry Failed Items: Again perform the migration for items that fail to arrive in the first run.
• Re-run Full Migration: Redo the entire migration again for all accounts directly skipping the setup stage.

Selective Data Filtering

Pick both start and end dates with the built-in Granular Date Selection menu. Use it to gain super precise control over what you migrate between two IMAP accounts. Save valuable time and server resources by excluding unnecessary data or users.

Concurrency Control Slider

Make the most optimal use of your system and network. A simple slider in the tool settings panel allows you to set the exact number of accounts that are to be migrated. Get maximum migration speed while putting minimum impact on your hardware.

Comprehensive IMAP Migration Reporting

Verify the success of inter-IMAP email transfer and maintain a complete audit trail with not one but two different end-of-process reports. Keep all records to share with stakeholders:

• Summary Report: Get an at-a-glance overview of success rate and total data size.
• Detailed Report: Receive an item-by-item log for every account that underwent IMAP migration.
