Cigati IMAP to Gmail Migration Tool
by Cigati Solutions
Migrate Emails From an IMAP Server to Gmail or Google Workspace
Switching to Gmail usually means one thing: your old mail has to come along. The Cigati IMAP to Gmail Migration Tool copies messages from any IMAP-enabled account into Gmail or Google Workspace. Your folder structure, attachments, sender and recipient details, timestamps, and read/unread status stay as they were.
It works for one mailbox or hundreds. Connect the source account, sign in to the Gmail destination, pick what to move, and start. Your source mailbox is only read, so nothing is changed or deleted on the old server unless you turn on the cleanup option yourself.
Why Use This Tool to Migrate IMAP Emails to Gmail
Keeps your folder hierarchy: Folders on the IMAP server appear in Gmail the way you organized them.
Preserves message details: Read/unread status, sender and recipient fields, timestamps, attachments, and supported metadata carry over.
Resumes after interruptions: If the network drops or the server times out, continue from where it stopped.
Removes duplicates: Repeated messages can be merged into a single entry based on the criteria you choose.
Frees up the old server: Optionally clear source data once the migration finishes successfully.
Runs on Windows and Mac: This software is available for both operating systems.
Advanced Email Filters: Narrow the job by Subject, From, To, CC, and BCC.
Skip Previously Migrated Emails: Re-running a job won't process the same messages twice.
Resume Migration: Pick up an interrupted transfer without starting over.
Batch CSV Migration: Add multiple IMAP accounts through one CSV file.
Migration Dashboard & Reports: Follow running, completed, and failed jobs, retry failed items, and export reports to check the results.

How the Migration Works
Launch the tool and choose IMAP as the source.
Enter the email address, IMAP host, port, and SSL/TLS details. You can sign in with a password, OAuth or an app password, depending on your provider.
Choose Gmail (Google Workspace) as the destination and log in to the target account.
Apply filters if you only need part of the mailbox: date range, sender, subject or recipient.
Set optional preferences such as duplicate removal, skipping Deleted Items, or cleaning the source afterward.
Start the migration and watch progress on the dashboard.
Security and Privacy
Data is encrypted while it is transferred.
Passwords are not stored for supported services.
Source mailboxes are accessed without changing or deleting anything.
The software installs on your own system, so mail stays inside your environment and does not pass through external servers.
Its approach fits GDPR-minded privacy needs, and it suits Managed Service Providers and small and medium businesses alike.
