Our Methodology

The Drish Infra 6-Phase Migration Framework

A battle-tested framework refined over 500+ migrations. Every step is designed to eliminate risk and ensure success.

1-2 weeks

Phase 01

Discovery & Assessment

Inventory all workloads, dependencies, performance baselines, and licensing. Identify migration candidates.

1 week

Phase 02

Strategy & Planning

Choose 6R strategy (rehost, replatform, refactor, repurchase, retire, retain) for each workload.

1-2 weeks

Phase 03

Architecture Design

Design target cloud architecture — networking, security, IAM, and service selection.

1-2 weeks

Phase 04

Proof of Concept

Migrate a non-critical workload end-to-end to validate approach, tooling, and team readiness.

2-8 weeks

Phase 05

Migration Execution

Phased migration with cutover windows, rollback plans, and real-time monitoring.

2-4 weeks

Phase 06

Optimization & Handoff

Post-migration tuning, cost optimization, documentation, and team training.

Migration Strategies

The 6R Framework

Not every workload should be containerized. We pick the right strategy for each application.

Rehost

Lift & Shift

Move as-is to cloud VMs. Fastest migration path with minimal code changes.

Effort: LowQuick win

Replatform

Lift & Optimize

Move to managed services — RDS instead of self-managed MySQL, for example.

Effort: MediumBetter performance

Refactor

Re-architect

Redesign for cloud-native — microservices, serverless, containers.

Effort: HighMaximum agility

Repurchase

SaaS Switch

Replace custom apps with SaaS — Salesforce, Workday, etc.

Effort: MediumLower TCO

Retire

Decommission

Turn off workloads no longer needed. Save on licensing and operations.

Effort: NoneCost savings

Retain

Keep On-Prem

Some workloads stay on-prem due to latency, compliance, or dependency.

Effort: NoneRisk avoidance

Cost Comparison

On-Prem vs Cloud TCO

We build detailed TCO models comparing your current on-prem costs against projected cloud costs — including migration investment and ongoing operations.

5-Year TCO Comparison

Hardware Procurement$800K$0
Software Licensing$400K$120K
Data Center (Power/Cooling)$300K$0
IT Staff (FTEs)$1.2M$480K
Cloud Services$0$600K
Migration Cost (One-time)$0$150K
Total 5-Year TCO$2.7M$1.35M

Risk Mitigation

We Eliminate Migration Risk

Pre-Migration Testing

Full cutover rehearsals in staging environments before touching production.

Rollback Plans

Every migration step has a documented rollback procedure. Instant recovery if needed.

Data Validation

Automated checksums and integrity verification at every stage of data transfer.

Monitoring & Alerts

Real-time dashboards during migration with instant alerts on any anomalies.

Migration Types

Every Migration Scenario, Covered

Data Center Migration

Full DC consolidation or closure. Move everything to cloud with decommissioning of physical assets.

Application Migration

Individual app migration with dependency mapping, testing, and cutover.

Database Migration

Schema conversion, data transfer, and performance validation for database platforms.

Mainframe Modernization

Transform legacy mainframe workloads into modern cloud-native applications.

Multi-Cloud Strategy

Distribute workloads across multiple cloud providers for resilience and optimization.

Hybrid Cloud Setup

Extend on-premises to cloud with secure connectivity, unified management, and burst capabilities.

Tools & Automation

Automated Migration Toolchain

We use industry-leading migration tools and custom automation to accelerate timelines and reduce human error.
