How It Works

Our Migration Process

A proven 6-step process that ensures successful IceWarp migration with minimal disruption.

Assessment

We analyze your IceWarp environment - version, domains, mailbox count, groupware usage, and special requirements. Free assessment with detailed migration plan.

Planning

Create migration schedule, set up destination environment, configure connections. Plan groupware and file sharing migration strategy.

Pre-Migration

Initial bulk migration while IceWarp remains active. Most data transferred during this phase with zero user impact. Users continue working normally.

Verification

Verify data integrity - compare mailbox counts, folder counts, calendar items, and random sampling. Identify and resolve any issues before cutover.

Delta Sync

Final sync to catch any new emails since pre-migration. Quick process - typically minutes. MX records updated to point to new platform.

Cutover & Support

DNS cutover to new platform. User communication and email client configuration support. Post-migration monitoring and issue resolution.

FAQ

Frequently Asked Questions

Answers to common questions about IceWarp email migration.

We migrate from all IceWarp versions including IceWarp 13.x (latest), 12.x, 11.x, 10.x, and older. We also support legacy Merak Mail Server versions (8.x, 9.x, 10.x). Both Windows and Linux installations are supported.

We migrate IceWarp to Microsoft 365 (Exchange Online), Google Workspace (Gmail), Exchange Server (on-premises 2013-2019), Zimbra, Zoho Mail, and other IMAP-compatible platforms. We also support IceWarp-to-IceWarp migrations for upgrades or consolidation, plus export to PST/MBOX/EML files.

We migrate all mailbox data: emails with attachments, complete folder structure, contacts (personal and shared), calendars (events, meetings, recurring items), tasks, notes, and groupware data including shared folders. Metadata like read/unread status and flags are preserved.

TeamChat and instant messaging history has limited migration options due to platform differences. For Microsoft 365, we can export chat history for archival. There is no direct migration to Teams. We discuss options during assessment and recommend the best approach for your needs.

Timeline depends on mailbox count and data volume. 1-50 mailboxes: 1-3 days. 50-200 mailboxes: 3-7 days. 200+ mailboxes: 1-2 weeks. Final cutover with delta sync typically takes minutes. We can work during off-hours/weekends.

Minimal to zero downtime. We perform initial bulk migration while IceWarp remains fully operational. Users continue working normally. Final cutover involves a quick delta sync (minutes) to catch new emails, then DNS/MX record update. Most users experience no interruption.

Pricing starts at $15 per mailbox for small migrations. Volume discounts: $12/mailbox (26-100), $10/mailbox (101-500), custom pricing for 500+. Includes all data types, groupware, delta sync, verification, and support. Free assessment provided - no obligation.

Absolutely. Merak Mail Server (the predecessor to IceWarp) is fully supported. We regularly migrate from Merak 8.x, 9.x, and 10.x versions to modern platforms. The process is essentially the same as IceWarp migration.

Typically yes - we need admin-level access to efficiently migrate all mailboxes. Options include: IceWarp Administration Console access, IMAP access with admin credentials, or API access for newer versions. We provide detailed instructions for each approach.

Yes, we migrate shared resources. IceWarp shared folders, shared calendars, and public folders are migrated where the destination platform supports equivalent features. For Microsoft 365, these become Shared Mailboxes or Microsoft 365 Groups. Permissions may need to be reconfigured.

Files are migrated. IceWarp WebDocuments and file sharing content migrates to OneDrive (M365) or Google Drive (Workspace). Folder structure is preserved. Share links will need to be recreated on the new platform.

Yes, typically. After migration, email clients (Outlook, Thunderbird, mobile apps) need to be reconfigured to connect to the new platform. For M365, this is often automatic with modern Outlook. We provide step-by-step guides for all common email clients.

Yes. We can migrate from IceWarp Cloud (hosted IceWarp) to Microsoft 365, Google Workspace, or other platforms. We just need appropriate access credentials - typically domain admin IMAP access or API credentials.

Absolutely. All data transferred over encrypted connections (TLS/SSL). We sign NDAs on request. Migration data is processed in secure environment and deleted after successful migration confirmation. We do not store or access your email content beyond technical requirements.

We recommend keeping IceWarp running (receive-disabled) for 2-4 weeks after migration as a backup reference. After you confirm everything is migrated successfully, you can decommission the server and cancel licensing. We do not modify or delete anything on your IceWarp server.
