Modernizing a healthcare or HealthTech product?
Legacy healthcare systems cannot be treated like ordinary enterprise software.
If your platform handles PHI, patient records, provider workflows, EHR data, FHIR or HL7 integrations, RPM data, clinical documentation, or regulated infrastructure, modernization needs a healthcare-specific approach.
Peerbits helps healthcare and HealthTech teams modernize legacy products using AI-assisted code analysis, PHI/data-flow risk mapping, FHIR/EHR readiness planning, phased refactoring, vendor handover support, and zero-disruption migration strategy.
AI helps us understand legacy systems faster. Healthcare engineers still own the architecture, compliance, QA, migration, and release decisions.

Our expertise that powers legacy modernization services
Our legacy modernization company provides deep technical capabilities across every layer of software modernization. From cloud migration to UI upgrades, our engineers rebuild legacy systems with secure and high-performing solutions for long-term business growth.
Cloud migration and modernization
We specialize in cloud modernization services by moving legacy workloads to AWS. We build scalable systems using containers, microservices, and serverless components.
Application re-engineering
Application re-engineering services include rewriting COBOL, VB, or PowerBuilder apps into modern stacks like .NET, Java, Node.js, or Python. We structure your applications for better maintainability and long-term growth.
Data modernization and migration
Migrate databases like DB2, Oracle, and SQL Server to modern RDBMS, cloud-native storage, or NoSQL systems. Our software modernization services maintain your data integrity and automate ETL workflows during transitions.
Integration and API enablement
Create APIs to connect legacy systems with cloud platforms, mobile apps, and third-party tools. Using MuleSoft, Kafka, and Apache Camel, we build integration layers that support your application modernization goals.
DevOps and automation
Add CI/CD pipelines, containerization, and orchestration to legacy systems using Docker, Kubernetes, and GitHub Actions. These DevOps practices speed up your rollout process and reduce deployment risks.
Security and compliance
Modernization plans follow industry standards like HIPAA, GDPR, and PCI DSS. We use encryption, tokenized access, and secure workflows, making us a reliable legacy modernization company for regulated sectors.
UI/UX modernization
Revamp your outdated front ends using React, Angular, or Vue to deliver responsive, accessible interfaces. These upgrades help drive better user adoption as part of your custom software modernization efforts.
Performance optimization

Book a strategy sessionFrequently asked questions
Warning signs include rising maintenance cost, slow performance, security gaps, limited support for new tech, and systems that no longer meet current business needs.
Timelines vary by system size and complexity. Small efforts may finish in a few months. Large-scale legacy modernization services can run longer. Phased delivery helps reduce disruption.
Common paths include rehosting, replatforming, refactoring, API wrapping, rebuilding, or full replacement. The right fit depends on goals, risk, and budget.
We apply current security controls, role-based access, encryption, audit logging, and alignment with regulations such as HIPAA, GDPR, and PCI DSS.
Cost depends on complexity, integrations, data volume, and selected modernization path. A structured assessment is needed to build an accurate estimate.
Data is profiled, backed up, migrated in stages, and validated. Strong planning lowers risk of loss or corruption and supports business continuity.
Use staged rollouts, pilot groups, parallel runs where needed, and thorough testing before cutover. Clear change management helps teams adapt.
No. Some can be integrated using APIs, some reworked, and some safely retired. Legacy application modernization is often selective, not all-or-nothing.
An iterative model supports incremental updates, earlier feedback, faster fixes, and visible progress without waiting for a single big release.
