Legacy & Custom System Migration with StrataMail

Organizations running Microsoft Exchange, Zimbra, MDaemon, or other on-premise mail systems face a common challenge: how to modernize email infrastructure without disrupting operations or forcing a "big bang" migration. StrataMail Hybrid Split Domain solution enables gradual migration, long-term coexistence, or selective cloud adoption while maintaining unified domain identity and centralized security.

The StrataMail Routing Cloud acts as an intelligent intermediary, handling inbound filtering, outbound relay, and smart routing across both your legacy systems and modern cloud platforms. Whether you're planning a phased migration to Microsoft 365, maintaining hybrid infrastructure for compliance reasons, or simply modernizing parts of your email stack, StrataMail provides the routing intelligence and security layer you need.

• Continue using Exchange, Zimbra, or other on-premise systems during migration
• Centralized filtering and security for all mailboxes, regardless of backend
• Smart routing based on user, department, or custom policies
• Support for phased migrations with automatic failover and monitoring
• Unified journaling, compliance, and audit logs across all mail platforms
