Challenges with Drupal
Key pain points
Here's the uncomfortable truth about Drupal: it's powerful, but it demands a level of investment that most teams underestimate. The learning curve is brutal. We're not talking about a weekend of tutorials; we're talking about months before a developer is truly productive. Drupal 8 and beyond adopted Symfony patterns, which is great for architecture but means you now need a PHP developer who also understands dependency injection, service containers, and YAML configuration files that seem to multiply overnight. Finding and retaining Drupal talent is genuinely difficult, and the developer survey data confirms it: fewer than 10% of the community is under 30, and almost nobody is joining fresh.
The upgrade story has been a recurring nightmare. The jump from Drupal 7 to 8 was essentially a full rebuild, and the ongoing churn from PHP and Symfony upstream changes means your team spends a meaningful chunk of time just keeping the lights on. Module compatibility breaks, themes need reworking, and the update process still isn't fully automated. If you're on a lean team, that maintenance burden is going to eat into your feature development time.
And then there's the content editor experience. Drupal was built by engineers for engineers, and it shows. The admin interface is functional but far from intuitive, and content teams coming from friendlier platforms consistently struggle with it. You can improve things with contributed modules and custom configuration, but that's more time and money. At the end of the day, if you don't have the budget for a dedicated Drupal team or a long-term agency partnership, you're going to have a bad time.
Punishing learning curve
Getting productive in Drupal takes months, not days. The combination of Symfony patterns, YAML configuration, and Drupal-specific conventions means onboarding new developers is slow and expensive.
Shrinking talent pool
The developer community is aging out. Fewer than 10% of Drupal developers are under 30, and new developers aren't joining at a rate that replaces those leaving. Finding affordable Drupal expertise is a real challenge.
Painful upgrade cycles
Between PHP version bumps, Symfony updates, and Drupal core changes, your team will spend significant time on maintenance that has nothing to do with shipping features. The Drupal 7 to 8 migration was so brutal they delayed end-of-life for years.
Poor content editor experience
The admin interface was designed by developers, and it shows. Content teams coming from WordPress, Sanity, or any modern CMS will find the editing experience clunky and unintuitive without significant customization.
Resource-hungry infrastructure
Drupal is not light. It demands proper server resources, caching layers, and database optimization to perform well. Cheap shared hosting won't cut it, and infrastructure costs add up quickly.
High total cost of ownership
It's open source, but don't let that fool you. Between specialized developers, hosting requirements, ongoing maintenance, and the sheer time investment to configure everything, Drupal projects consistently cost more than teams expect.
Benefits of Adobe Experience Manager
Key advantages
AEM is the kind of platform you only choose if you’re a Fortune 500 company or enjoy voluntarily suffering. I hate anything Adobe builds. It’s bloated, overpriced, and aggressively designed to lock you into their ecosystem. But fine, here are the positives: the Adobe integration is unmatched. If your entire organisation already lives inside Creative Cloud, Analytics, and Target, AEM becomes this giant DXP monolith that handles assets, personalization, segmentation, and multi-channel delivery without breaking a sweat. The DAM is legitimately powerful, and it scales like a tank.
If you’re not operating at scale, you’ll spend absurd money for problems a clean Sanity + modern composable stack solves better and cheaper. If you are considering AEM or escaping it, get in touch. We’ll help you choose something that won’t haunt your ops team for the next decade.
Integration with Adobe tools
AEM connects with Creative Cloud, Analytics, and Target, letting teams move assets, data, and personalisation logic across tools without friction
Robust digital asset management
The DAM is genuinely powerful. It has AI tagging, smart cropping, versioning, and bulk optimisation for massive media libraries.
Consistent multi-channel delivery
AEM can push content to web, mobile apps, email, and more from one central source. Ideal for enterprises that need consistent messaging across every customer touchpoint.
Flexible architecture
Supports both classic and headless approaches, letting teams mix legacy setups with modern frontends. It’s adaptable enough for companies with complicated stacks.
Scalable enterprise-level operations
AEM is designed to handle huge traffic, global teams, and heavy workflows. It scales reliably when backed by proper infrastructure and Adobe’s cloud.
Intuitive user interface
For an enterprise platform, the UI is relatively approachable, helping large content teams manage complex workflows without needing to touch code.
Common questions
Drupal to Adobe Experience Manager migration FAQs
Answers to the most common questions about Drupal to Adobe Experience Manager migration
How do I migrate a website from Drupal?
We export your content, taxonomy, user data, and media from Drupal's database, then restructure everything for the target platform. Most Drupal migrations we handle move to Sanity or a headless setup with Next.js. The timeline depends on how many content types, custom modules, and Views you're running. A typical mid-size site takes 4-8 weeks. The hardest part is usually untangling custom module logic and rebuilding it in a modern stack.
What are the best Drupal alternatives?
For enterprise projects that need structured content and granular permissions, Sanity is our top recommendation. It matches Drupal's content modelling depth without the PHP overhead or the shrinking talent pool. For simpler sites that were on Drupal because someone chose it 10 years ago, WordPress or even Webflow might be enough. The right alternative depends on whether you actually need Drupal's power or just inherited it.
How do I migrate from Drupal 7 to a modern CMS?
Drupal 7 reached end-of-life, so this is urgent for many teams. Rather than migrating to Drupal 10 (which is essentially a rebuild anyway), most of our clients choose to move to a headless CMS instead. We extract your Drupal 7 content using Drush and custom migration scripts, then map it to the new platform's schema. The frontend gets rebuilt in Next.js or a similar framework. It's a bigger project than a version upgrade, but you end up with a system that's actually maintainable long-term.
How much does a Drupal migration cost?
It varies wildly based on content volume, custom modules, and frontend complexity. A small Drupal site with 500 pages might cost $15,000-$30,000 to migrate. Enterprise Drupal sites with thousands of pages, custom workflows, and multilingual content can run $50,000-$150,000+. The honest truth is that Drupal migrations are expensive because the platform is complex. But the ongoing savings from reduced hosting costs, easier maintenance, and cheaper developer rates usually justify the investment within 12-18 months.
Is Drupal still worth using in 2026?
Only if your project genuinely needs what Drupal offers, meaning deep content modelling, granular permissions, and multilingual support at scale. For government and large institutional sites, it still makes sense. For everything else, the shrinking developer pool, high maintenance costs, and painful upgrade cycles make it hard to justify. We've moved many teams off Drupal who were paying $200+/hour for specialized developers when a modern headless setup would have served them better at a fraction of the ongoing cost.
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.
