Microsoft BizTalk Server Product Lifecycle Update

For more than 25 years, Microsoft BizTalk Server has supported mission-critical integration workloads for organizations around the world. From business process automation and B2B messaging to connectivity across industries such as financial services, healthcare, manufacturing, and government, BizTalk Server has played a foundational role in enterprise integration strategies.

To help customers plan confidently for the future, Microsoft is sharing an update to the BizTalk Server product lifecycle and long-term support timelines.

BizTalk Server 2020 will be the final version of BizTalk Server.

Guidance to support long-term planning for mission-critical workloads

This announcement does not change existing support commitments. Customers can continue to rely on BizTalk Server for many years ahead, with a clear and predictable runway to plan modernization at a pace that aligns with their business and regulatory needs.

(*) Paid Extended Support will be available for BizTalk Server 2020 between April 2028 and April 2030 for customers requiring hotfixes for non-security updates. CSS will continue providing their typical support. BizTalk Server 2016 is already out of mainstream support, and we recommend those customers evaluate a direct modernization path to Azure Logic Apps.

Continued Commitment to Enterprise Integration

Microsoft remains fully committed to supporting mission-critical integration, including hybrid connectivity, future-ready orchestration, and B2B/EDI modernization. Azure Logic Apps, part of Azure Integration Services — which includes API Management, Service Bus, and Event Grid — delivers the comprehensive integration platform for the next decade of enterprise connectivity.

Host Integration Server: Continued Support for Mainframe Workloads

Host Integration Server (HIS) has long provided essential connectivity for organizations with mainframe and midrange systems. To ensure continued support for those workloads, Host Integration Server 2028 will ship as a standalone product with its own lifecycle, decoupled from BizTalk Server. This provides customers with more flexibility and a longer planning horizon. Recognizing Mainframe modernization customers might be looking to integrate with their mainframes from Azure, Microsoft provides Logic Apps connectors for mainframe and midrange systems, and we are keen on adding more connectors in this space. Let us know about your HIS plans, and if you require specific features for Mainframe and midranges integration from Logic Apps at: https://aka.ms/lamainframe

Azure Logic Apps: The Successor to BizTalk Server

Azure Logic Apps, part of Azure Integration Services, is the modern integration platform that carries forward what customers value in BizTalk while unlocking new innovation, scale, and intelligence.  With 1,400+ out-of-box connectors supporting enterprise, SaaS, legacy, and mainframe systems, organizations can reuse existing BizTalk maps, schemas, rules, and custom code to accelerate modernization while preserving prior investments including B2B/EDI and healthcare transactions.

Logic Apps delivers elastic scalability, enterprise-grade security and compliance, and built-in cost efficiency without the overhead of managing infrastructure. Modern DevOps tooling, Visual Studio Code support, and infrastructure-as-code (ARM/Bicep) ensure consistent, governed deployments with end-to-end observability using Azure Monitor and OpenTelemetry.

Modernizing Logic Apps also unlocks agentic business processes, enabling AI-driven routing, predictive insights, and context-aware automation without redesigning existing integrations. Logic Apps adapts to business and regulatory needs, running fully managed in Azure, hybrid via Arc-enabled Kubernetes, or evaluated for air-gapped environments.

Throughout this lifecycle transition, customers can continue to rely on the BizTalk investments they have made while moving toward a platform ready for the next decade of integration and AI-driven business.
