Cross-Cloud Migration for a Global Insurance Enterprise

A large global insurance enterprise with a significant production footprint in Google Cloud Platform (GCP) needed to migrate to Microsoft Azure to align with enterprise platform standards. The migration required high-fidelity replication of infrastructure across cloud providers, accurate service and SKU mapping, and minimal operational disruption throughout the transition.

The Challenge

Business Challenge

Traditional approaches to cross-cloud discovery, documentation, and migration would have required months of manual effort — and introduced substantial compliance and operational risk. The client needed:

  • Accurate, complete discovery of the existing GCP production environment
  • Precise mapping of services and SKUs between GCP and Azure
  • Safe re-deployment of applications and migration of data at scale
  • Full validation of the new environment before cutover to avoid downtime
  • Architecture documentation and operational runbooks for long-term maintainability

Enterprise Solution Guide

The End of Manual Cloud Delivery

Cloud transformation initiatives rarely fail because of vision — they fail when execution becomes too manual, fragmented and difficult to scale.

Our executive guide outlines how enterprise leaders can leverage AI to reduce operational drag, accelerate modernization and vastly improve delivery across complex cloud environments.

The Solution

AI-Powered Cloud Platform

Aditi led the engagement under its Migration & Modernization model, applying the AI-Powered Cloud Platform to compress the discovery-to-deployment timeline while maintaining architectural fidelity, compliance integrity, and full audit traceability. Aditi's architects directed AI-accelerated delivery across all migration phases:

  • Read-only integration with GCP to extract full infrastructure configuration — no manual audit required, zero production impact
  • Automated documentation of the existing environment, including all dependencies, configurations, and data relationships
  • AI-driven service and SKU mapping between GCP and Azure equivalents — eliminating weeks of manual cross-referencing
  • Infrastructure as Code (IaC) generation for the Azure target environment, reviewed and validated by Aditi architects before deployment
  • Deployment through GitHub pipelines into target Azure environments — consistent, repeatable, auditable
  • Digital twin creation enabling full end-to-end testing and validation prior to DNS cutover — eliminating go-live risk
  • Automated generation of architecture diagrams, technical documentation, and operational runbooks — client-owned and ready for ongoing operations

Timeline

~75% — Reduction in migration timeline (2 months → 2 weeks)

Full discovery, environment mapping, and infrastructure replication completed in 2 weeks — compared to a typical timeline of approximately 2 months. Testing, validation, and cutover followed shortly after, with the legacy GCP environment successfully decommissioned.

The Outcome

Business Outcomes

  • ~75% reduction in migration timeline — 2 months compressed to 2 weeks
  • Accelerated evidence collection and documentation — audit-ready from day one
  • Significantly reduced migration risk through digital twin validation prior to cutover
  • Consistent, repeatable infrastructure deployment using Infrastructure as Code throughout
  • Faster service mapping and cross-cloud replication — AI eliminated weeks of manual cross-referencing
  • Architecture diagrams and operational runbooks delivered — client-owned for long-term maintainability
  • Successful decommissioning of the legacy GCP environment on schedule

"What used to take
months now takes
weeks"

— with better governance,
stronger documentation,
and zero production risk.
