Modernising Spark’s Digital Foundation: AEM Cloud Migration

The Project

Anchora was engaged by Spark NZ to lead the modernisation of their digital experience platform, migrating from legacy on-premise Adobe Experience Manager (AEM) to AEM as a Cloud Service. The initiative spanned Spark’s core digital properties including their React-based SPA, knowledge base sites, brand sites, 150+ Adaptive Forms, and a network of API integrations, all requiring a carefully phased approach to manage complexity and minimise risk to live operations.

The Ask

Spark required a strategic migration partner with deep AEM expertise to modernise their digital foundation without disrupting the experiences their customers and internal teams rely on daily.
 
Key requirements included:
  • Reduced Operational Overhead: Move away from costly, self-managed on-premise infrastructure to Adobe-managed cloud services.
  • Improved Reliability & Performance: Deliver a scalable, high-performance platform across Spark’s core digital properties.
  • Simplified Release Management: Replace manual deployment cycles with automated CI/CD pipelines via Adobe Cloud Manager.
  • Cloud-Native Enablement: Unlock Adobe’s modern innovation roadmap, including Assets, Adaptive Forms, Dynamic Media, and advanced integrations.
  • Modern Front-End Architecture: Enable React-based front-end frameworks and headless, microservices-ready integration patterns.

Scope

Anchora executed a phased, multi-stream migration across six parallel workstreams, deliberately avoiding a “big bang” approach to manage risk and accelerate time-to-value:
  • Spark SPA Migration: Migrated Spark’s React-based single page application into AEMaaCS, including full revalidation of integrations and front-end components.
  • Knowledge Base Sites (Atamai & Tautoko): Migrated with complete content integrity and integration continuity across both knowledge base properties.
  • Skinny & Skinny Jump: Additional brand sites brought into the new cloud architecture with consistent governance and deployment standards.
  • Legacy Site Assessment: Conducted a deep technical assessment of legacy sites, classified and right-sized as non-migratable, providing Spark with a clear, evidence-based blueprint for future content rationalisation.
  • Forms Migration: Migrated ~150 Adaptive Forms into AEM 6.5, retaining dynamic schemas, validation logic, and backend integrations.
  • OAuth Implementation: Built a scalable new token service layer, replacing basic authentication across SPA and Knowledge Base API calls.
  • Modern Engineering Foundations: Stood up fully automated Cloud Manager CI/CD pipelines, Dev + RDE environments with branching discipline, federated identity via Adobe Admin Console, and cloud-enabled content sync using Content Sets.
  • Knowledge Transition: Delivered full documentation and knowledge transfer into Spark’s internal systems to ensure long-term platform ownership.

Outcome

The migration was completed successfully across all workstreams, delivering significant and measurable impact:
  • 40–60% Reduction in Platform Maintenance: Adobe-managed infrastructure removed the burden of self-hosted operations, freeing Spark’s internal teams for strategic work.
  • ~30% Faster Deployment Cycles: Cloud Manager CI/CD pipelines replaced manual processes, accelerating time-to-market for digital changes.
  • Zero Downtime Upgrades: Cloud-native architecture enabled seamless updates without service interruption.
  • Improved Security Posture: Continuous compliance and automated patching replaced manual security management.
  • Unified Governance: Adobe Admin Console with federated access delivered consistent role-based control across Spark’s digital estate.
  • Future-Proof Platform: Spark now has a scalable digital foundation ready for React-driven experience layers, headless and microservices integration, and Adaptive Forms expansion across broader business workflows.
Beyond the original scope, Anchora provided on-demand support for out-of-scope defects, rebuilt portions of legacy code to validate feasibility, and helped Spark re-frame their future migration roadmap, creating a clear blueprint for long-term digital modernisation.
