Challenges with Adobe Experience Manager

Key pain points

AEM’s biggest flaw is simple: everything about it is expensive. The license, the hosting, the maintenance, the consultants, the upgrades, and the people required to even use it. The learning curve is a cliff, implementation cycles move at glacial speed, and the UI feels like punishment for asking to edit content. Performance tanks the moment you customise anything, and collaboration is basically “email the PDF and pray.” If you ever see the word specialised in an AEM context, just assume the invoice comes with an extra zero.

It’s the definition of a heavyweight DXP built for organisations with more bureaucracy than sense. For everyone else, it becomes a slow-moving, over-engineered system that requires Adobe-certified babysitters just to stay alive. If you’re considering scrapping it for something faster, saner, and built this decade, we can help you migrate without dragging the AEM baggage along for the ride.

High complexity and cost

High complexity and cost

AEM is one of the most expensive CMS/DEXP platforms on the market, with licensing, hosting, and maintenance costs that only make sense for very large enterprises.

Steep learning curve

Steep learning curve

The platform is dense and requires specialised training just to perform routine tasks. Most teams can’t operate it without dedicated experts.

Prolonged implementation periods

Prolonged implementation periods

Even simple projects take months. Rollouts, upgrades, and workflow changes move slowly and require careful planning to avoid breaking things.

Challenging navigation of capabilities

Challenging navigation of capabilities

AEM packs in a huge feature set, but finding and configuring what you actually need can feel like wading through molasses.

Necessary reliance on Adobe partners

Necessary reliance on Adobe partners

You’re essentially forced into using Adobe-certified agencies or consultants for setup, maintenance, and troubleshooting and they don’t come cheap.

Not ideal for smaller companies

Not ideal for smaller companies

The cost, complexity, and operational overhead make AEM a poor fit for startups or mid-sized teams. Most will drown in it long before they benefit from it.



Benefits of KeystoneJS

Key advantages

KeystoneJS is one of those tools that really clicks if your team thinks in code. It's a schema-driven, open-source headless CMS built on Node.js, and the developer experience is genuinely good. You define your content models in TypeScript, Keystone generates a GraphQL API and an admin UI for you, and you're off. There's very little magic or abstraction hiding what's happening under the hood, which we appreciate when building complex projects for clients.

The Prisma ORM integration is a real highlight. Automatic migration generation, type-safe database access, and support for PostgreSQL, MySQL, and SQLite mean you're not fighting your data layer. If you've ever had to wrangle a CMS into supporting a non-trivial relational content model, you'll understand why this matters. Keystone lets you express those relationships cleanly and query them with a proper GraphQL API.

The document field editor is also worth mentioning. It's one of the more thoughtful rich text implementations we've seen in a headless CMS. You can embed custom React components directly into the editor, which means content teams can work with your actual design system components rather than generic blocks. For teams that care about structured content, Keystone gives you real tools to enforce it.

Where Keystone really shines is in projects where the development team wants full ownership of the stack. There's no vendor lock-in, no proprietary query language, and no surprise pricing tiers. If you want a CMS that feels like a well-designed library rather than a platform, Keystone delivers on that promise.

Common questions

Adobe Experience Manager to KeystoneJS migration FAQs

Answers to the most common questions about Adobe Experience Manager to KeystoneJS migration

How much does Adobe Experience Manager cost?
AEM is one of the most expensive CMS platforms going. Adobe publishes no list prices, so everything is a custom enterprise quote. From contracts we've seen, AEM Sites licensing tends to start around $60,000 per year on its own, and a full AEM as a Cloud Service deployment usually lands in the six figures, often $200,000 or more annually once you factor in usage. Implementation runs another $100,000 to $500,000+, and Adobe support contracts add 15-25% of licensing on top. We've watched companies pay more for their AEM contract than for their entire engineering team's salaries. If that ratio sounds familiar, it's time to rethink the stack.
Can I migrate from AEM to Sanity?
Yes, and it's one of the more common moves we handle. The work is real but tractable. For an enterprise instance, plan for a few weeks to a few months depending on how customised AEM is. The biggest bottleneck is content extraction. AEM's JCR (Java Content Repository) stores everything in a proprietary node structure that needs custom tooling to export cleanly. Custom OSGi bundles, Sling models, and heavy DAM workflows all get rebuilt or replaced, usually with something far simpler. We run a parallel build, standing up Sanity and a modern frontend while AEM stays live, then cut over once content and redirects are validated. Editorial teams keep working throughout.
What are AEM's main limitations?
Cost is the headline, but it isn't the only one. Development is slow because nearly everything routes through Java, OSGi, and Sling, so even small changes need a dedicated dev. Performance degrades the moment you customise the platform. The author UI is dense, and routine content work often still depends on engineers. You're also tied to Adobe-certified partners for setup and upkeep, and contracts tend to carry multi-year lock-ins. The headless side (Content Fragments served over GraphQL, plus the Universal Editor) works, but it's bolted onto a DXP monolith rather than built lean from the start.
Is AEM overkill for most sites?
For most sites, yes. AEM earns its keep when an organisation already lives inside Creative Cloud, Analytics, and Target and needs governance across hundreds of properties. If you're not using several of those Adobe tools, you're paying enterprise rates for a CMS that's slower to build on and more expensive to staff than the alternatives. We've met teams who adopted AEM on a consultant's recommendation, then found they used maybe 15% of it. A Sanity backend with a Next.js frontend would have cost a fraction and shipped faster. Three things to watch if you do leave. DAM assets with custom metadata and renditions don't transfer automatically. Dispatcher and Sling URL patterns need careful redirect mapping to hold SEO value. Contract lock-ins can carry steep early-termination fees.
What makes migrating from KeystoneJS difficult?
KeystoneJS stores data through Prisma, so the database layer is well-structured and easy to export. The harder part is replacing everything Keystone doesn't give you. Most Keystone projects have custom-built preview systems, publishing workflows, and access control logic that are tightly coupled to the Node.js backend. Rebuilding those features in a new CMS takes planning. We typically budget 4 to 8 weeks for a Keystone migration depending on how much custom infrastructure the team has built around it.
Why do teams move away from KeystoneJS?
Deployment complexity is the number one reason. Teams love Keystone during local development, then hit a wall getting it reliably into production. The Docker images can balloon past a gigabyte, the docs don't cover production hosting well, and there's no managed hosting option. The small community compounds this problem. When you hit an edge case, there are fewer people who've solved it before. Content editors also struggle with the admin UI, which lacks visual editing, live preview, and built-in publishing workflows that competing platforms ship by default.
How do we extract our content from KeystoneJS?
Since Keystone uses Prisma ORM, your content lives in standard PostgreSQL, MySQL, or SQLite tables with clean schemas. You can export directly from the database using SQL dumps or Prisma's query API. The content model is defined in your TypeScript codebase, so mapping fields to a new CMS is straightforward. We write automated scripts that handle the data transformation, including resolving relationships between lists and migrating file references. For a project with 20 to 50 Keystone lists, extraction and transformation usually takes 1 to 2 weeks.
