The easiest way to migrate from BizTalk

Companies relying on BizTalk must start planning their migration now. With Frends, you can lower costs, simplify integrations and reuse your existing code, extensions and artifacts. 

Don’t let BizTalk’s end-of-life disrupt your business

As Microsoft announced April 11, 2028, as the last day for its mainstream BizTalk support, companies are facing a pressing question: how to migrate complex integrations without disrupting systems or affecting their business. Not only that, working with BizTalk came with its own set of challenges. 

Complex workflows

BizTalk’s complex integration workflows required a specific set of technical skills while having technical limitations that grew over the years 

Costly maintenance

Many IT teams relied on external consultants that were well versed in the complex BizTalk environment which requires costly manual maintenance 

Lack of innovation

Rising risks and technical debt have been a reality for the BizTalk environment due to the lack of development and no new versions since 2020

Seamless code migration

One of the most significant advantages of choosing Frends for BizTalk migration is the ability to preserve and reuse existing investments. You can:
  • Reuse C# code completely: Existing BizTalk C# code can be fully reused with simple copy-pasting operations
  • Preserve .NET extensions: All existing .NET extensions remain functional and can be integrated into the new platform
  • Convert orchestration logic: BizTalk Orchestration Logic can be converted to Frends-compatible BPMN 2.0 using the proprietary Migration Toolkit
  • Maintain deployment environments: The existing BizTalk deployment environment can be used as-is, with no need to reconfigure servers or port settings

Improved technical features

The platform handles contemporary integration requirements including REST APIs, modern messaging protocols, and cloud-native communication patterns that BizTalk struggles to support without extensive customization.

Frends offers flexible deployment options:

  • Hybrid architecture: Seamlessly combine on-premises and cloud capabilities, allowing data to remain in specific security segments when required
  • Multi-cloud support: Deploy across multiple cloud platforms and legacy systems, ensuring continuity and operational efficiency in complex IT landscapes

FAQ

Microsoft is ending mainstream support for BizTalk Server by 2028, and BizTalk will no longer receive further investment or updates. However, waiting until the last minute is risky. Migration efforts are more complex than most organizations expect, and delaying creates increasing technical debt. Additionally, staying on BizTalk means you lose access to modern capabilities like AI-powered automation, improved developer experience, and innovation advantages that your competitors may already be leveraging. 

Frends offers radical simplification compared to BizTalk. Instead of managing a complex, monolithic platform with specialized expertise requirements, you get: 

  • One unified platform: One tool, one UI, one skillset instead of BizTalk's complexity. 
  • Dramatically lower TCO: Reduced need for specialized teams and simpler operations. 
  • Transparent, process-based pricing: No complex licensing models or hidden costs. 
  • Ranked #1 on G2 for Usability: Consistently highest rated for ease of setup and implementation. 
  • Modern AI capabilities: Agentic AI orchestration that BizTalk simply cannot offer. 

Yes, absolutely. Frends supports a phased, side-by-side migration approach, which is the recommended best practice. You can run both platforms simultaneously and gradually migrate integrations one by one, significantly reducing risk. This allows you to: 

  • Test and validate each integration before decommissioning the BizTalk version. 
  • Maintain business continuity throughout the migration. 
  • Prioritize which integrations to move first based on business value and complexity. 

Because Frends is .NET-native (built on .NET 8), you can reuse substantial portions of your BizTalk logic: 

  • C# Code: Custom C# logic can often be reused directly or with minimal changes. 
  • XSLT Transformations: XSLT with inline C# can be migrated by converting C# functions to custom XSLT functions, or by modernizing to JSON-based transformations using C# code. 
  • Business Logic: Core business rules and integration patterns can be mapped to BPMN 2.0 workflows, potentially requiring less effort than complete rewrites. 

Yes. Frends provides automated migration scripts for common scenarios: 

  • .NET Framework to .NET Standard 2.0 migration tool: Successfully used by customers like Helen to migrate several hundred processes. 
  • Automated conversion with manual guidance: The tool performs automatic conversions where possible and generates a list of items that require manual intervention, such as task version updates. 
  • .NET 8 migration support: Analysis tools are available for customers targeting the latest .NET runtime. 

The main challenges organizations face include: 

  • XSLT transformations with inline C# code: Require analysis and reimplementation strategies. 
  • Custom adapters and pipelines: May need to be rebuilt using Frends Tasks or custom code. 
  • Complex orchestrations: Require mapping to BPMN 2.0 process models. 
  • Cross-platform considerations: If moving from Windows-only BizTalk to containerized or Linux-based Frends Agents. 
  • Specialized integrations: Legacy systems (e.g., Cobalts, older web services) may need modernization. 

Frends migration specialists can assist with assessment and planning to address these challenges systematically. 

Yes. Frends is the only iPaaS available via the Azure Marketplace with MACC (Microsoft Azure Consumption Commitment) credits. This means you can: 

  • Use existing Azure commitment funds to purchase Frends. 
  • Simplify procurement through the Azure Marketplace. 
  • Maximize the value of your Microsoft investment. 

This is a significant advantage for Microsoft-centric organizations with existing Azure Enterprise Agreements. 

Several organizations have successfully migrated from BizTalk to Frends with impressive results: 

  • Tokmanni: Achieved 60% cost reduction and 12x faster problem-solving. 
  • MuniFin: Replaced legacy BizTalk to modernize integrations while ensuring resilience and compliance in the financial sector. 
  • Helen: Successfully migrated several hundred processes using Frends migration tools. 
  • Nurminen Logistics & Pite Energi: Completed BizTalk migrations in logistics and energy sectors respectively. 

These organizations benefit from lower operational costs, faster development cycles, and access to modern capabilities like AI-powered automation. 

Beyond solving the end-of-support issue, Frends provides continuous innovation and modern capabilities: 

  • AI-powered automation: Native Intelligent AI Connector for document processing, classification and decision-making — capabilities impossible in BizTalk. 
  • Superior developer experience: Intuitive visual design, faster onboarding and lower training costs. 
  • Real-time monitoring: Modern observability and monitoring dashboards for proactive issue resolution. 
  • Cloud-native scalability: Dynamic scaling in containerized environments (Kubernetes, AKS). 
  • Active innovation roadmap: Continuous platform updates, new connectors and features aligned with modern integration needs. 
  • Vendor viability: Frends is actively investing in the platform, unlike BizTalk's sunset trajectory. 

Migrating to Frends is more than just replacing a deprecated platform. It's giving your integration strategy the modernization it needs for the next decade.
