Migrate to Modern Kubernetes — Without the Risk

Containerize legacy apps, build Helm charts, establish CI/CD, and execute zero-downtime cutover from VMs or legacy platforms to EKS, AKS, or GKE. Including managed upgrade paths for EKS 1.x and migration to Google Anthos or Azure Arc.

Duration: 1-3 months Team: 1-2 Senior K8s Engineers

You might be experiencing...

Running on legacy VMs, ECS, or outdated K8s versions with no clear migration path
Afraid of downtime during migration — business cannot afford interruption
Team lacks containerization and K8s expertise to execute safely
Previous migration attempt failed or stalled halfway

Engagement Phases

Weeks 1-2

Assessment & Planning

Workload discovery, containerization readiness scoring, migration strategy per application (rehost, replatform, refactor). EKS version upgrade path planning for clusters on 1.x.

Weeks 2-4

Foundation

Cluster provisioning with IaC (Terraform), networking, RBAC, observability stack, CI/CD pipeline, container registry.

Weeks 4-10

Migration Execution

Batch migration with Dockerfiles, Helm charts, testing, and blue-green cutover per application. Google Anthos or Azure Arc migration for hybrid/multi-cloud scenarios.

Weeks 10-12

Optimization & Decommission

Right-size resources, enable autoscaling, decommission old infrastructure, documentation and training.

Frequently Asked Questions

How do you achieve zero-downtime migration?

We use blue-green cutover per application. The new Kubernetes environment runs in parallel with your existing infrastructure, we verify functionality under load, and then switch traffic. If anything goes wrong, traffic reverts to the original environment instantly.

How long does a typical Kubernetes migration take?

Typical migrations run 1-3 months depending on the number of applications. Weeks 1-2 cover assessment and planning, weeks 2-4 handle cluster provisioning with Terraform and GitOps setup, weeks 4-10 execute batch migration, and weeks 10-12 focus on optimization and old infrastructure decommission.

Can you migrate from Docker Swarm, ECS, or legacy VMs?

Yes. We migrate workloads from VMs, Docker Swarm, ECS, older Kubernetes versions, and bare-metal deployments. Each application gets a migration strategy — rehost, replatform, or refactor — based on its complexity and requirements.

Do you support Google Anthos or Azure Arc migration scenarios?

Yes. For organizations running hybrid or multi-cloud infrastructure, we support migration to Google Anthos for unified management across on-premises and GCP clusters, and Azure Arc for extending Azure management to non-Azure clusters. We design the migration path based on your existing infrastructure and target operating model.

What if we are on EKS 1.x and need to upgrade?

We design a managed upgrade path for EKS clusters on older Kubernetes versions. This includes pre-upgrade compatibility checks, API deprecation audits using Pluto, blue-green upgrade execution with rollback capability, and post-upgrade validation. We handle each minor version increment safely.

What deliverables do we receive?

You receive a production-ready K8s cluster provisioned with Terraform, Dockerfiles and Helm charts for all migrated applications, CI/CD pipelines with image scanning, an observability stack, zero-downtime cutover execution, and operational runbooks for your team.
