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.
Phase 01
Discovery & Assessment
Inventory all workloads, dependencies, performance baselines, and licensing. Identify migration candidates.
Phase 02
Strategy & Planning
Choose 6R strategy (rehost, replatform, refactor, repurchase, retire, retain) for each workload.
Phase 03
Architecture Design
Design target cloud architecture — networking, security, IAM, and service selection.
Phase 04
Proof of Concept
Migrate a non-critical workload end-to-end to validate approach, tooling, and team readiness.
Phase 05
Migration Execution
Phased migration with cutover windows, rollback plans, and real-time monitoring.
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 & ShiftMove as-is to cloud VMs. Fastest migration path with minimal code changes.
Replatform
Lift & OptimizeMove to managed services — RDS instead of self-managed MySQL, for example.
Refactor
Re-architectRedesign for cloud-native — microservices, serverless, containers.
Repurchase
SaaS SwitchReplace custom apps with SaaS — Salesforce, Workday, etc.
Retire
DecommissionTurn off workloads no longer needed. Save on licensing and operations.
Retain
Keep On-PremSome workloads stay on-prem due to latency, compliance, or dependency.
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

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
