Connect every system. Move off BizTalk with confidence.
We design, build and run integrations on Azure (APIs, workflows, EDI and events) and migrate BizTalk Server estates to Azure Integration Services step by step, without disrupting the business.
The clock is running.
Source: Microsoft Lifecycle, BizTalk Server 2020. Large estates often take 12–24 months to migrate.
The Azure integration toolkit
Six building blocks, one modern platform.
Azure Integration Services is a family of managed services that together cover everything BizTalk did, with cloud scale, pay-as-you-go pricing and modern DevOps.
Logic Apps
Workflows that orchestrate processes, transform XML and JSON, apply business rules and connect to hundreds of systems.
Service Bus
Enterprise messaging with queues and topics: guaranteed delivery, retries and publish/subscribe. The modern MessageBox.
API Management
One secure front door for all your APIs: authentication, rate limits, versioning, analytics and a partner portal.
Event Grid
Real-time event routing. React the moment a file lands, an order is placed or a record changes.
Azure Functions
Serverless C# for the custom logic BizTalk handled in pipeline components and helper classes.
Integration Account
B2B and EDI for trading partners (X12, EDIFACT and AS2), with partners, agreements, schemas and maps in one place.
Reference architecture
How it fits together.
Messages come in through APIs or events, Logic Apps orchestrate and transform them, Service Bus delivers them reliably, and everything is secured and monitored centrally.

Every BizTalk feature has a modern home.
We map each BizTalk component to its Azure equivalent and reuse what we can. XSD schemas and XSLT maps often carry over directly.
| BizTalk Server | Azure Integration Services |

| Receive ports & locations | Logic Apps triggers and API Management |
| Send ports | Logic Apps actions and connectors |
| Orchestrations | Logic Apps workflows (Standard) |
| MessageBox (publish / subscribe) | Azure Service Bus topics and Event Grid |
| Maps (XSLT) | Logic Apps XML transforms and Data Mapper |
| Schemas (XSD) | Reused in Logic Apps or an Integration Account |

| Business Rules Engine | Azure Logic Apps Rules Engine |
| Adapters (SQL, SAP, FTP, File, MQ) | Built-in and managed connectors, on-premises data gateway |
| Trading partners, EDI & AS2 | Integration Account (B2B: X12, EDIFACT, AS2) |

How we work
A proven six-step migration path.
BizTalk and Azure run side by side the whole way. We move interfaces in small, tested waves, so there is never a risky big-bang weekend.

Assess
We inventory every BizTalk application (ports, orchestrations, maps, schemas, adapters and custom code) plus message volumes and dependencies.
Plan
We group interfaces into waves by risk and value, choose rebuild or re-platform for each, and design the target architecture.
Build the foundation
Networking, security, Key Vault, monitoring and CI/CD pipelines, set up as infrastructure as code with Bicep or Terraform.
Migrate in waves
We start with a low-risk pilot, then move interfaces wave by wave, reusing schemas and maps wherever possible.
Test in parallel
Automated tests plus side-by-side runs against BizTalk prove each interface produces the same results before the switch.
Cut over & support
We switch traffic, provide hypercare, decommission BizTalk servers and train your team to run the new platform.

Fixed quotePilot migration
One real interface moved end to end to Azure, to prove the approach before you commit.
Fixed quoteFull migration program
Every interface migrated in planned waves, with testing, cutover and decommissioning.
Custom quoteManaged integration
We monitor, support and improve your Azure integrations every month after go-live.
Monthly quoteWhy move now
More than beating a deadline.
No servers to patch
Managed services replace the BizTalk servers, SQL clusters and host instances you maintain today.
Pay for what you use
Consumption and flexible plans instead of large up-front licence and hardware costs.
Scale automatically
Handle seasonal peaks and new partners without buying capacity in advance.
Modern DevOps
Infrastructure as code, automated deployments and full monitoring from day one.
Connect to the cloud
Hundreds of ready-made connectors, plus a data gateway for on-premises systems.
Ready for AI
Once your data flows through Azure, adding AI steps to workflows is straightforward.
Common questions
Do we have to migrate everything at once?
No. BizTalk and Azure run side by side while we move interfaces in waves, starting with a low-risk pilot.
Can we reuse our maps and schemas?
Often, yes. XSD schemas and XSLT maps can usually be reused in Logic Apps. Custom code is reviewed case by case.
What about on-premises systems?
They stay connected. The on-premises data gateway lets Azure workflows securely reach SQL, files, SAP and more.
How long does a migration take?
It depends on the number of interfaces, orchestrations and custom components. Small estates can move in a few months; large ones take a year or more. Try the estimator above for a first idea.
Can you support our BizTalk environment while we migrate?
Yes. We can monitor and fix the existing BizTalk setup during the migration, so the business keeps running until each interface is switched.
Will our running costs go up on Azure?
Not necessarily. Many teams save by retiring servers and licences. We model the expected Azure cost in the assessment, before you commit.
