Cloud migration — done with eyes open

Cloud migration across the six Rs (rehost, replatform, refactor, repurchase, retire, retain). On-prem to AWS/Azure/GCP, cloud-to-cloud, with regulator-aware data movement.

What we deliver

The capabilities our Cloud Migration engineers ship.

Production patterns from real engagements — not a stack-marketing checklist.

  • 01

    Migration assessment

    Workload inventory, dependency mapping, six-Rs classification, business case, regulator-aware data movement plan.

  • 02

    Migration planning

    Wave sequencing, parallel-run strategy, rollback procedures, risk register, business-continuity plan.

  • 03

    Lift-and-shift

    Fastest path — VMware to AWS, on-prem databases to managed services. Operational continuity prioritised over modernisation.

  • 04

    Replatform & refactor

    Containerisation, serverless adoption, managed-database migration (e.g., MySQL to Aurora, MS SQL to Azure SQL Managed Instance).

  • 05

    Regulatory-grade data movement

    RBI, CBK, FCA, CBUAE-aware data movement. Encryption in transit + at rest, audit trail, regulator notification.

  • 06

    Post-migration modernisation

    Cloud-native rebuild for high-strategic-value workloads. Once-migrated workloads don't stay lift-and-shift forever.

Who hires us for Cloud Migration

Where this stack fits best.

We've seen the patterns — match yours against the list to find the closest fit to your situation.

  • On-prem enterprises

    Large enterprises with significant on-prem investment, migrating to cloud for cost, agility or capacity reasons.

  • BFSI under regulator scrutiny

    Banks, insurers and lenders moving regulated workloads to cloud — needs careful regulator engagement.

  • Cloud-to-cloud migrations

    Companies consolidating multi-cloud sprawl or moving between hyperscalers.

  • Cost-pressured migrations

    Companies whose on-prem costs (or wrong-cloud costs) have outgrown the business model.

  • Data centre exit

    Companies exiting data centre leases or end-of-life hardware refresh decisions.

How we engage

From brief to production.

Transparent, milestone-driven, with clear owners and timeframes at every stage.

  1. 01Weeks 1–3

    Discovery & assessment

    Workload inventory, dependency mapping, six-Rs classification per workload, business case, regulator scan.

  2. 02Weeks 4–6

    Migration planning

    Wave sequencing, target architecture, parallel-run strategy, rollback procedures, risk register, BCM plan.

  3. 03Weeks 6–10 (parallel)

    Foundation

    Landing-zone setup (IAM, network, security, observability, FinOps), Terraform foundation, CI/CD pipelines.

  4. 04Months 3–12

    Wave execution

    Phased migration by wave. Each wave: prepare → cutover → parallel run → cut-over confirmation → rollback if needed.

  5. 05Per workload

    Post-migration modernisation

    For strategic workloads — containerisation, serverless, managed-services adoption. Lift-and-shift doesn't have to stay there.

Cloud Migration in depth

Inside our Cloud Migration practice.

The long-form view of how we approach Cloud Migration engagements.

Six Rs of migration

Cloud migration is not one thing — it's six. Rehost (lift-and-shift), Replatform (lift-and-reshape), Refactor (re-architect), Repurchase (replace with SaaS), Retire (decommission), Retain (keep on-prem). The right answer depends on the workload, the timeline, the budget and the strategic value. Most migrations are a mix.

What we deliver

  • Migration assessment — workload inventory, classification by R, business case
  • Migration planning — sequencing, dependencies, risk register, parallel-run strategy
  • Execution — actual migration with rollback procedures
  • Modernisation post-migration — once in the cloud, the real work begins
  • Application modernisation — containerisation, serverless, managed-services adoption

We pair this with our AWS/Azure/GCP expertise and BFSI-aware regulatory experience.

Why Redian for Cloud Migration

What makes our Cloud Migration practice different.

Independent reasons clients pick us over freelancers, agencies and large consultancies.

  • Six-Rs honest

    We classify workloads honestly. Sometimes the right answer is to retire or retain — not migrate. We say so.

  • Regulator-aware

    BFSI migrations under RBI, CBK, FCA, CBUAE supervision. Data residency, audit trails, regulator notifications handled.

  • IaC foundation

    Terraform landing-zone from day one. No ClickOps migrations. Disaster recovery is automated, not aspirational.

  • Modernisation included

    We don't stop at lift-and-shift. Strategic workloads get modernised post-migration — containerisation, serverless, managed services.

Frequently asked questions

Everything you wanted to ask before the call.

Don't see your question? Ask us directly →

How long does a cloud migration take?

Small workload (single app): 4–12 weeks. Mid-size estate (20–50 apps): 6–12 months. Large enterprise (100+ apps): 12–36 months. Phased by waves so business value flows continuously.

Six Rs — should every workload be the same R?

Definitely not. Most migrations mix lift-and-shift (R1) for legacy apps approaching end-of-life, replatform (R2) for adoptable managed services, refactor (R3) for strategic apps, and retire/retain for the rest. We classify honestly.

What about regulated workloads (BFSI)?

Most regulators (RBI, CBK, FCA, CBUAE) now permit cloud adoption with conditions. We engage regulators early, design audit trails, ensure data residency where required, and document cloud control attestations.
