[Anshu_123]

Migrating from IceWarp to SmarterMail can be done efficiently using the IMAP protocol, as both email servers support it. This ensures a smooth transfer of mailbox data such as emails and folders without complex configurations.

Manual Method (Using IMAP Migration)​

SmarterMail provides a built-in migration tool that allows importing data from third-party mail servers via IMAP.

Steps to migrate IceWarp to SmarterMail:

1. Prepare the Source (IceWarp)
   • Ensure IMAP service is enabled for all mailboxes.
   • Keep user credentials (email & password) ready.
   • Take a complete backup of IceWarp data for safety.
2. Set Up SmarterMail Server
   • Install and configure SmarterMail.
   • Create user mailboxes matching IceWarp accounts.
3. Use SmarterMail Migration Tool
   • Log in to SmarterMail.
   • Navigate to Settings → Connectivity → Mailbox Migration.
   • Enter IceWarp IMAP server details (hostname, port, credentials).
   • Choose IMAP as the protocol, then start the migration.
4. Monitor Migration
   • The process runs in the background, and data appears gradually.
   • Users can continue working during migration.
5. Verify Data
   • Check emails, folders, and structure after completion.

IMAP migration is recommended because it preserves folder hierarchy, message dates, and read/unread status.

Limitations of the Manual Method​

• Requires user credentials for each mailbox
• Time-consuming for large-scale migrations
• Limited migration of contacts, calendars, and other data
