It’s official. The countdown is on.
BizTalk Server 2020 is entering its final phase of support. Mainstream support ends in January 2025, and extended support runs until April 2030. That might seem far away, but for any organisation still relying on BizTalk to keep systems connected, the time to act is now.
Modernising integration takes time. These environments are rarely simple. Leaving it too late could mean rushed decisions, higher costs, or limited options.
So what does end of support really mean for your business, and what should you be doing today to prepare?

Why BizTalk End of Support Matters
The BizTalk SFTP adapter is often used for secure, automated exchanges of files with third-party syMicrosoft has confirmed:
- Mainstream support ends: January 2025
- Extended support ends: April 2030 (security updates only)
This means no new features, no non-security bug fixes, and no innovation.
If you’re still running older versions, you might already be outside the support window entirely, exposing your business to risk.
This is especially critical for teams in regulated industries or any business with compliance, performance, or security expectations.
You Might Be More Dependent Than You Think
BizTalk has been part of enterprise estates for decades. It quietly handles:
- File transfers
- APIs
- Routing
- Messaging
- System orchestration
The challenge? Many teams don’t fully understand everything it’s doing — until it’s time to move away. Documentation fades. Staff move on. And BizTalk becomes a silent but critical dependency.

What You Should Be Thinking About Now
Audit your current BizTalk usage
What applications, orchestrations, ports, and pipelines are active? This is your foundation.
- Assess the risks – Are you running unsupported components? Outdated protocols? Custom code or third-party adapters?
- Define your modernisation goals – Are you migrating to Azure? Rebuilding from scratch? Hoping to decommission BizTalk entirely?
- Look for early wins – Identify what’s loosely coupled or well documented — start modernising there.
- Build a roadmap – Break the transition into phases. Replace what’s feasible now. Plan to phase out the rest over time.

What Are the Alternatives?
Depending on your goals and architecture, explore:
- Azure Logic Apps
Prebuilt connectors and workflows for cloud/hybrid integration.
- Azure Integration Services
A scalable platform for enterprise-grade integration.
- Durable Functions / Microservices
Great for custom orchestration with full control.
- Third-party platforms
For industry-specific requirements or non-Microsoft stacks.
- Hybrid models
Keep BizTalk in place temporarily while introducing modern tools in parallel.

This Is More Than Just a Technical Milestone
BizTalk’s end of support is a rare opportunity to step back and rethink your integration strategy.
If BizTalk is still at the heart of your architecture, the question isn’t if you should modernise.
It’s when, how, and with what support in place.
