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
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
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
Even simple projects take months. Rollouts, upgrades, and workflow changes move slowly and require careful planning to avoid breaking things.
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
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
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 Kentico
Key advantages
If Corporate Memphis art, dashboards, and spreadsheets are what you need, Kentico might be your happy place. The interface feels like Microsoft Office; that is, it is familiar, editor-friendly, and hard to break. And unlike platforms that need 14 plugins and a prayer, Kentico ships with the whole toolkit. It has marketing automation, e-commerce, workflows, multisite, multilingual, and the entire lot.
It scales well, handles heavy enterprise workloads, and integrates cleanly through APIs. But it is not the right fit for tiny brochure sites, but for large organizations that want everything under one roof, it’s a serious contender. If you’re unsure whether you really need the full armoury, send it our way and we’ll tell you if you’re ready for Kentico or if you’re just buying a tank to deliver pizza.
User-friendly interface
Kentico’s UI feels familiar with “Office toolbar,” like functions, rather than “developer terminals.” Editors can publish, schedule, and update content without needing a developer on standby.
Built in tools
You don’t need to glue together 12 plugins just to run campaigns or sell products. Kentico ships with automation, personalization, analytics, and e-commerce baked in.
Flexible API and extensibility options
If your team speaks .NET, Kentico supports it. Its APIs and integration options make it easier to connect CRMs, ERPs, BI tools, and custom services without duct-tape engineering.
Workflow and role management system
It has multiple approvers, granular permissions, and strict publishing rules. Legal, marketing, and IT can all sign off without stepping on each other.
Fast onboarding + safe staging
Training is quick, publishing is simple, and staging environments keep mistakes from going live. Teams can work confidently without “oops, wrong button” moments.
Headless-ready
If you want speed, security, and headless flexibility, Kentico delivers. Content moves fast, scales well, and supports multi-site or multilingual setups without falling over.
Common questions
Adobe Experience Manager to Kentico migration FAQs
Answers to the most common questions about Adobe Experience Manager to Kentico migration
How much does Adobe Experience Manager cost?
AEM is one of the most expensive CMS platforms on the market. Adobe doesn't publish list prices, but AEM Sites licensing typically starts around $60,000 per year on its own, and full AEM as a Cloud Service deployments usually land in the $200,000 to $300,000+ range annually. Implementation adds $500,000 to $1M, and Adobe support contracts add another 15-25% of licensing on top. We've seen companies paying more for their AEM contract than their entire engineering team's salaries. If that ratio sounds familiar, it's time to rethink the stack.
How long does it take to migrate off Adobe Experience Manager?
Plan for 4-8 months minimum for a full migration, depending on how customised your AEM instance is. The biggest bottleneck is usually content extraction. AEM's JCR (Java Content Repository) stores everything in a proprietary node structure that requires custom tooling to export cleanly. If you've built custom OSGi bundles, Sling models, or heavy DAM workflows, those all need to be rebuilt or replaced. Our approach is to run a parallel build, standing up the new stack while the old one stays live, then cutting over once everything is validated. That way editorial teams never lose a day of productivity.
Is AEM worth it for companies not using the full Adobe suite?
Honestly, no. AEM's biggest advantage is its tight integration with Creative Cloud, Analytics, Target, and the rest of the Adobe ecosystem. If you're not using at least three or four of those tools, you're paying a premium for a CMS that's slower to develop on, harder to maintain, and more expensive to staff than modern alternatives. We've worked with companies who adopted AEM because a consultant recommended it, only to discover they were using 15% of its capabilities. A well-architected headless CMS with a Next.js frontend would have cost them a fraction of the price and shipped faster.
What do you need to watch out for when leaving AEM?
Three things catch teams off guard. First, asset migration. AEM's DAM often holds thousands of assets with custom metadata, renditions, and smart crops that don't transfer automatically. Second, URL structures. AEM's dispatcher and Sling resource resolution create URL patterns that need careful redirect mapping to preserve SEO value. Third, Adobe contracts. Many AEM agreements include multi-year lock-ins with steep early termination fees. Check your contract terms before you start planning the migration timeline. We always audit all three of these before scoping any AEM migration project.
How much does a Kentico migration typically cost?
Kentico migrations are enterprise-scale projects. For a site with 1,000 to 10,000 pages, expect the migration itself to run 8 to 16 weeks of development time. The cost depends on how deeply you've customised Kentico's marketing automation, e-commerce, and workflow features. Simple content-only migrations are faster, but most Kentico installations have years of custom .NET logic that needs to be rebuilt or replaced. We've seen total migration budgets range from $30,000 to $150,000 depending on scope, which still often pays for itself within 18 months through reduced licensing and maintenance costs.
Why are companies migrating away from Kentico?
Licensing costs are the initial trigger for most conversations we have. Kentico's annual fees add up fast, especially when you include maintenance, hosting, and the cost of .NET developers to keep it running. But the deeper issue is agility. Major version upgrades introduce breaking changes that can destabilise sites with years of custom logic. The admin UI feels dated as projects scale. Multi-tenant setups carry real risk since one bad customisation can take down every site in the cluster. Teams eventually decide the operational overhead isn't worth it.
What's the biggest challenge when migrating from Kentico?
Untangling the all-in-one features. Kentico bundles marketing automation, e-commerce, analytics, workflows, and content management into one platform. When you migrate away, each of those capabilities needs a new home. Content goes to your new CMS, email automation might move to a tool like Resend or Customer.io, and e-commerce might need a dedicated platform. We map out every feature your team actually uses before writing a single migration script, because the biggest risk is discovering a dependency mid-project that nobody documented.
