Is it possible to migrate existing emails to 138 without losing messages?

Yes, 138 Enterprise Email supports migration from existing systems, ensuring message integrity during the transition. The process is officially managed and follows a structured procedure to preserve emails, contacts, and calendar data. Successful migration depends on domain verification, access credentials to the source system, and compatibility with IMAP/POP protocols. Before starting, ensure your domain is bound to 138 Enterprise Email and that you have administrative access to both platforms. Migration can be completed through the official service portal, which provides guided steps for configuration and synchronization. For complex migrations, direct-operated support is available to assist with setup and validation. While data loss is minimized, it is recommended to back up critical data before proceeding. Contact the official support team for step-by-step guidance based on your specific migration scenario.
