IMAP Migration Scenarios and Use Cases

EdbMails supports single and bulk mailbox projects, source-to-target mapping, selective migration, concurrent mailbox processing, incremental follow-up passes, and migration reports. Authentication varies by provider: Microsoft 365 target connections use modern authentication, while source IMAP authentication depends on the source service and account policy.

Standard IMAP migration is primarily email-focused. It can transfer supported messages, attachments, folders, folder hierarchy, and common message properties that the source exposes and the target accepts. Contacts, calendars, tasks, rules, and other non-mail workloads are not available through standard IMAP and require a separate provider-specific or application-specific workflow.

This page is the scenario hub for EdbMails IMAP migration. Use it to choose the source-to-target workflow that matches your project, then follow the dedicated commercial and step-by-step page for that scenario. For the main product overview, features, licensing, and generic IMAP migration capabilities, see the EdbMails IMAP Migration Tool.

IMAP to Office 365 (Microsoft 365) Migration

Use the dedicated IMAP to Office 365 migration workflow to move supported email data from IMAP-enabled sources such as Gmail, Zimbra, Zoho Mail, cPanel, GoDaddy, Rackspace, and other providers to Microsoft 365 mailboxes. Prepare the target users, review mailbox mapping, run a pilot, and verify the migration before mail-flow cutover.

For staged projects, run follow-up incremental passes for eligible new or changed email items before the final cutover. Source authentication requirements vary by provider, while the Microsoft 365 target connection should use the current EdbMails modern-authentication workflow.

Key Benefits:

• Direct migration from IMAP servers to Microsoft 365 mailboxes
• Simultaneous transfer of multiple mailboxes to reduce overall migration time
• Microsoft 365 target authentication through the current EdbMails modern-authentication workflow

Supported Scenarios:

• Gmail to Office 365 migration
• Zimbra to Office 365 migration
• cPanel to Office 365 migration
• GoDaddy to Office 365 migration
• Rackspace to Office 365 migration
• Icewarp to Office 365 Migration

IMAP to Exchange Migration

Use the IMAP to Exchange migration workflow to move supported email data from IMAP mailboxes to a supported on-premises or hosted Exchange environment. Microsoft ended support for Exchange Server 2016 and 2019 on October 14, 2025; Exchange Server Subscription Edition (SE) is Microsoft's current supported on-premises release. If your target is a legacy Exchange environment, verify both its vendor support status and current EdbMails compatibility before migration.

Review target mailbox provisioning, Exchange permissions, message-size limits, mailbox mapping, filtering, and target-side verification before increasing migration concurrency or completing the cutover.

Key Benefits:

• Migration to supported on-premises or hosted Exchange environments
• Bulk mailbox loading and source-to-target mapping
• Selective email migration using supported filters
• Incremental follow-up passes for staged cutover
• TLS-secured network connections where supported by the environment

Supported Scenarios:

• Gmail to Exchange Migration
• Zoho Mail to Exchange Migration
• Yahoo Mail to Exchange Migration
• Zimbra IMAP to Exchange Migration
• cPanel to Exchange Migration

  Steps to migrate IMAP to Exchange server

IMAP to IMAP Migration

Use the IMAP to IMAP migration workflow when changing email providers, consolidating accounts, or moving mail between IMAP-enabled systems. EdbMails can load single or multiple accounts, map source and target mailboxes, preserve supported folder hierarchy and message properties, and run follow-up incremental passes for staged projects.

Key Benefits:

• Transfer supported email data between IMAP-enabled source and target servers
• Preserve supported folder hierarchy and common email properties
• Automatic and manual mailbox mapping
• Incremental follow-up migration for eligible new or changed email items
• Supports same-domain and cross-domain migration where both servers permit IMAP access

Supported Scenarios:

• Zimbra to Gmail migration
• cPanel to cPanel migration
• Rackspace to Gmail migration
• Rackspace to AWS migration
• Gmail to Tutanota migration

IMAP to PST Export

Use the IMAP to PST Converter and Backup Tool to create Outlook PST copies of supported IMAP email data for offline backup, archiving, mailbox handoff, or retention projects. For large exports, review storage capacity and use PST split options where appropriate instead of relying on one oversized PST file.

Key Benefits:

• Export IMAP mailboxes directly to PST format
• Maintain original folder hierarchy and email metadata
• Supports bulk mailbox export
• Ideal for long-term backup or retention needs

Supported Scenarios:

• Gmail to PST export
• Zimbra to PST export
• Yahoo Mail to PST export
• cPanel to PST export
• Zoho Mail to PST export

PST to IMAP Migration

PST to IMAP is the reverse workflow: the source is an Outlook PST file and the destination is an IMAP mailbox. EdbMails can import supported PST email data into IMAP accounts for restoration or consolidation. This remains a separate PST-owned migration intent, so use the dedicated PST to IMAP migration page for instructions.

Key Benefits:

• Import PST data into IMAP mailboxes securely
• Maintain folder structure and metadata
• Supports multiple PST imports in batches
• Ideal for restoring or consolidating old mailbox data

Supported Scenarios:

• Import PST Files to Gmail
• PST Files to Zimbra Migration
• Import PST Files to Zoho Mail
• Import PST Files to Outlook
• Migrate PST Files to GoDaddy

Summary of EdbMails IMAP Migration Scenarios

Common EdbMails Capabilities Across IMAP Scenarios

• Concurrent mailbox processing: EdbMails processes 10 mailboxes concurrently by default and can be configured up to 20 where source, target, network, and migration-system limits permit.
• Scenario-specific authentication: Authentication depends on the source and target provider; Microsoft 365 targets use the current EdbMails modern-authentication workflow.
• Incremental follow-up passes: Eligible new or changed email items can be processed in subsequent runs for supported migration scenarios.
• Selective migration: Use supported filters and folder exclusions to reduce unnecessary transfer volume.
• Mailbox mapping: Review automatic mappings and make manual corrections where source and target identities differ.
• Migration reports: Use mailbox and folder status, item counts, errors, and warnings to verify the operation.
• 24/7 technical support: EdbMails provides migration assistance through its support channels.
