Legacy Migration Services
Modernize Legacy Systems, Reduce Technical Debt & Enable Cloud-Native Transformation
Enterprises rely on decades-old legacy applications, ESBs, databases, and custom-built systems that were never designed for today’s API-driven, cloud-first digital world. These legacy systems create technical debt, slow down innovation, limit integration capabilities, and increase maintenance cost.
Boominger delivers end-to-end Legacy Migration Services to modernize outdated systems into cloud-native architectures using modern iPaaS platforms (Boomi, Azure Integration Services, SAP CPI), microservices, APIs, and event-driven workflows — without disrupting business operations.
🔍 What Is Legacy Migration?
Legacy migration is the structured modernization of:
Old ESB systems (TIBCO, BizTalk, IBM IIB, WSO2, SAP PI/PO)
Custom monolithic applications
On-prem middleware & integration layers
Outdated data pipelines and ETL systems
Legacy databases & storage systems
Hard-coded batch processes and point-to-point connections
It includes:
Replatforming → moving from on-prem to cloud
Refactoring → rewriting components for cloud
Re-architecting → API-first, event-driven, microservices
Replacing → introducing modern SaaS / iPaaS platforms
Rebuilding → modern integration flows (APIs, iFlows, Logic Apps)
Our approach ensures reduced technical debt, lower cost, and improved scalability.

🟦 Our Legacy Migration Services
1. Legacy Assessment & Roadmapping
We begin with a deep analysis of:
Current application & integration landscape
System dependencies & data flows
Business-critical processes
Security posture & compliance requirements
Technical debt analysis
Migration effort estimation
Deliverables include:
Modernization roadmap
Risk & dependency mapping
Coexistence model for phased migration
Integration modernization blueprint
2. Legacy Integration Extraction & API Enablement
We break down legacy systems into modern, reusable components:
Expose legacy functionalities as APIs
API layer for monolith systems
Event-driven integration extraction
Adapter replacement strategy for legacy ESBs
Standardized patterns: sync APIs, async messaging, workflows
This enables API-first digital transformation.
3. Migration to Modern iPaaS & Cloud Platforms
We migrate workloads into scalable cloud-native platforms:
Target platforms include:
Boomi
Azure Integration Services
SAP CPI
Event-driven services
Microservices
Cloud databases & storage
Migration includes:
Redesigning legacy mappings
Re-implementing logic into iFlows / Logic Apps
API gateway integration
Security hardening
Automated deployment pipelines
4. Legacy Application Refactoring
For custom applications, we deliver:
Monolith → microservices architecture
Serverless modernization (Azure Functions)
Containerization (AKS / Docker)
Code refactoring & modularization
5. Data Migration & Modernization
We modernize legacy data pipelines:
ETL → ELT workflow migration
Real-time streaming (Event Hub / Kafka)
Batch-to-stream transformation
Data warehouse → cloud analytics migration
Master data synchronization
6. Legacy System Decommissioning
Once cloud migration is complete, we handle:
Decommissioning old ESB/app servers
Operational handover
Cleanup of unused components
Cost optimization & documentation
🟨 Legacy Migration Use Cases
Replace aging ESB with cloud iPaaS
Move SAP PI/PO interfaces to SAP CPI
Modernize BizTalk or TIBCO integrations
API-enable on-prem ERP or core systems
Migration to cloud databases & analytics
Event-driven transformation for real-time flows
B2B & EDI modernization
🟪 Legacy vs Modern Integration – Why Migrate?
| Legacy Systems | Modern Cloud Platforms |
|---|---|
| High maintenance cost | Pay-as-you-go model |
| Complex deployments | CI/CD automation |
| Limited visibility | Full observability & monitoring |
| Hard-coded logic | Configurable low-code flows |
| Slow changes | Rapid development cycles |
| On-prem only | Cloud, hybrid & multi-cloud |
Legacy migration enables speed, agility, and operational resilience.

Legacy Migration FAQs
Is legacy migration risky?
Not with phased coexistence and dependency mapping.
Do you migrate TIBCO/BizTalk/SAP PI/PO systems?
Yes — we specialize in legacy ESB to cloud iPaaS modernization.
Can we API-enable legacy systems instead of replacing them?
Yes — API wrapping is a common modernization pattern.
Do you help refactor monolith applications?
Yes — into microservices or serverless architectures.
Do you provide 24×7 support?
Yes — with enterprise SLAs.
