Beyond 'Lift and Shift': CMS migration requires a strategic partner

Clemente Pereyra, September 9, 2025

As digital strategies evolve, businesses often look to adapt their technology stack to meet evolving goals. While a robust, enterprise, end-to-end platform like Adobe Experience Manager (AEM) is excellent for integrated digital experiences, a flexible, API-first CMS like Sanity is often preferred for a composable architecture. When a project requires this kind of strategic re-platforming, the process is far more than a simple "lift and shift" operation. It's a pivotal opportunity to reassess, restructure, and future-proof your entire content ecosystem.

Simply moving content isn't enough. A successful migration requires a deep understanding of both the source and target platforms, a strategic approach to content modeling, and a partner who can navigate the complexities to ensure a seamless transition. This is where 3|SHARE excels.

The migration experts: Deep knowledge in both AEM and Sanity

As an Adobe Platinum Solution Partner, our expertise in AEM is second to none. We have spent years designing, implementing, and managing complex AEM solutions for leading global clients. We are also a certified Sanity partner, giving us a unique and powerful advantage. We don't just understand the technology; we understand the nuances of your content, how it's structured in AEM, and how it should be structured in Sanity to meet your business goals.

Our migration services are built on this dual expertise. We don’t just move your data; we elevate your content strategy. We help you:

  • Assess: We start by analyzing your current AEM setup, identifying what works, what doesn’t, and where opportunities for improvement lie.
  • Re-think: We work with you to redesign your content structure based on your current and future needs, ensuring your new Sanity setup is optimized for flexibility and scalability.
  • Propose: We deliver a comprehensive migration plan that covers both the technical solution and the operational processes, aligning everything with your core business objectives.
  • Accelerate: We speed up the entire migration process, for both content structures and the content itself, minimizing risk and downtime.

Our secret weapon: The 3|SHARE AEM-to-Sanity Migration Tool

To deliver on our promise of a fast, high-quality migration, we’ve developed a proprietary migration tool that automates and streamlines the most critical phases of the process. This accelerator is a core component of our service, designed to handle the complexities of moving structured content from AEM to Sanity with precision and speed.

Our tool’s three core features ensure a seamless transition:

  • A. Schema Generation: The foundation of any Sanity project is its schema. Our tool ingests AEM Content Fragment Model definitions and automatically generates corresponding, functional Sanity schemas. This eliminates weeks of manual work and ensures your new structure is a perfect match for your existing models.
  • B. AEM Tag Migration: Taxonomy and metadata are vital for content discoverability and organization. We handle the migration of AEM tags, mapping them to a custom Sanity Tag document to preserve these crucial relationships. This ensures that all references within your content fragments remain intact.
  • C. Content Ingestion: We extract content directly from AEM Content Fragments and generate a single, clean ndjson file. This file can be imported directly into your Sanity dataset, preserving all content, metadata, and references in a single, efficient operation.

Your partner for a future-ready CMS

Migrating from AEM to Sanity is a strategic move that can unlock incredible potential for your business. But the success of the project hinges on the quality of the execution. With 3|SHARE, you get more than a vendor; you get a partner with unparalleled expertise in both platforms and a proven methodology for success.

Let us help you make the move, not just by migrating your content, but by transforming your content strategy for the future.
