Migration Methodology

The 6 R’s Cloud Migration Strategy

We evaluate your application portfolio against AWS and Azure best-practice 6R strategies to select the fastest, lowest-risk, and most cost-effective path.

Fastest Cloud Transition1–3 Weeks

Rehost (Lift & Shift)

Moving existing on-premise VMs and databases directly into AWS EC2 or Azure VMs with minimal architectural code modifications.

Best When:
Urgent data center lease expirations or immediate disaster recovery requirements.
3–6 Weeks

Replatform (Lift & Reshape)

Upgrading underlying OS and moving databases to managed cloud services (AWS RDS Aurora / Azure SQL) without altering core business logic.

Best When:
Eliminating database management overhead while retaining core legacy software code.
6–12 Weeks

Refactor (Re-Architect)

Re-engineering legacy monoliths into cloud-native microservices, containerized Kubernetes apps, and serverless functions.

Best When:
High-growth applications demanding infinite auto-scaling, high availability, and rapid feature velocity.
2–4 Weeks

Repurchase (Drop & Shop)

Replacing custom non-differentiating legacy modules (e.g. email servers, basic helpdesks) with modern SaaS platforms.

Best When:
Retiring commoditized internal software to focus engineering budget on proprietary differentiation.
Immediate

Retire (Decommission)

Auditing server fleets to identify and shut down redundant, legacy, or unused applications and database instances.

Best When:
Immediate 10% to 20% cloud and infrastructure cost savings.
Continuous

Retain (Hybrid Cloud Encapsulation)

Keeping strict compliance or latency-critical hardware on-premises while wrapping them with secure cloud API gateways.

Best When:
Banking, military, or regulated hospital mainframes with strict physical data residency mandates.
Architecture Modernization

When Tailored Cloud-Native Modernization Beats Blind Lift-and-Shift Tools

Automated lift-and-shift migration scripts replicate on-prem inefficiencies directly into the cloud, resulting in astronomical compute bills, unmanaged idle VMs, and zero architectural resilience. Custom cloud modernization restructures workloads into elastic, cost-efficient cloud-native powerhouses.
