Overview

Migration Done Once, Done Right

Cloud migrations fail when they're treated as lift-and-shift exercises. Moving VMs to EC2 isn't cloud-native — it's cloud-hosted legacy. ICF approaches every migration as a transformation opportunity: re-platform where it makes sense, containerise where it doesn't, and eliminate what's no longer needed.

We've written custom Golang tooling to automate large-scale source control migrations preserving full commit history, migrated artifact repositories serving hundreds of teams, and moved GitLab runner fleets from self-hosted VMs to managed Kubernetes — each time with a tested rollback plan and a staged cutover that keeps production running throughout.

Capabilities

What We Deliver

Workload Migration

  • Discovery and dependency mapping of all workloads before migration starts
  • Containerisation of legacy applications for Kubernetes deployment
  • Re-platform from bare-metal / VMs to managed AWS or GCP services
  • Database migration with logical replication and zero-downtime cutover
  • Staged migration with parallel-run validation before decommission

Artifact Repository Migration

  • Nexus to AWS CodeArtifact: Maven, npm, PyPI, Docker registries
  • Artifactory to GCP Artifact Registry migration with policy migration
  • Repository access control and token migration
  • CI/CD pipeline reconfiguration for new registry endpoints
  • Artifact retention policy design and cost optimisation

Source Control Migration

  • SVN, BitBucket Server, or TFS to GitHub / GitLab Cloud
  • Custom Golang tooling for bulk repository migration with full history
  • Branch protection rules, webhooks, and CI trigger migration
  • Team and permission structure migration
  • Developer communication and training for the new workflow

CI/CD Runner Migration

  • Self-hosted Jenkins to GitHub Actions or GitLab CI SaaS
  • GitLab self-hosted runner fleet to managed Kubernetes runners on GKE or EKS
  • Job rewrite with caching and concurrency optimisation
  • Secret migration to GitHub / GitLab native secrets or Vault
  • Cost analysis: runner fleet TCO vs. hosted minutes
How We Work

Our Approach

01

Discovery & Audit

Full inventory of workloads, dependencies, and data flows. Identify migration waves by risk and complexity.

02

Migration Strategy

Target architecture design, tooling selection, rollback procedures, and success criteria defined before any migration begins.

03

Pilot Migration

Migrate the lowest-risk workload first. Validate the tooling, process, and rollback plan in production before committing to the full migration.

04

Full Migration & Decommission

Wave-by-wave migration with parallel running. Decommission only after full validation. Complete documentation of the new state.

When to Engage

Is This Right for You?

You're paying for a data centre lease that's coming up for renewal

A lease renewal date is the perfect forcing function for a migration. We help you design the cloud target architecture and execute before the deadline.

Your Jenkins setup is a maintenance nightmare no one wants to touch

Jenkins to GitHub Actions or GitLab CI SaaS migrations eliminate the self-hosting burden and give developers a faster, more consistent CI experience.

Your Nexus or Artifactory server is a single point of failure

Managed artifact registries (CodeArtifact, Artifact Registry) eliminate server maintenance and provide HA and cross-region replication out of the box.

A company acquisition brought a different cloud or toolchain

Post-merger technical integration — consolidating source control, pipelines, and artifact repositories into a unified toolchain — is work we've done before.
