Challenges with Kentico
Key pain points
Here’s the reality check about Kentico. It isn’t cheap. Licensing, implementation, and support can feel like a CFO jump-scare. And while the interface is friendly at first glance, once you get into migrations, upgrades, or deeper customisation, things get… heavy.
Major version updates can introduce breaking changes, permissions get messy at scale, and multi-tenant setups mean one bug can take down every project sharing the stack. The docs and community aren’t as deep as the open-source world either, so when something goes wrong, you’ll likely need a developer rather than a forum thread to save you. If you can absorb the overhead and like Corporate Memphis art, go ahead. But before you go ahead, give us a call, and we will try to set up a better solution for you.
Steep learning curve
Kentico’s power comes with complexity. Newcomers and smaller teams often need time (and developers) to actually start working.
High cost for licenses and maintenance
Licensing and maintenance can add up quickly, which makes Kentico a harder sell for startups or smaller organizations.
Upgrades can get messy
Major version jumps, migrations, or deep API changes sometimes introduce breaking changes, which, trust us, is not fun if your site has years of custom logic.
UI feels dated at scale
As projects grow, the dashboard can get cluttered and less intuitive. It works, but it’s not winning design awards, unless you are still competing in 2015.
Limited community support.
Support exists, but the ecosystem isn’t as loud or as active as WordPress (not our first choice), Webflow, or headless-first platforms like Sanity.
Customizations risk impacting all sites
In multitenant setups, a poorly built custom feature can impact every site in the cluster, which means you can't move or change a single line of code, unless you love 404 messages.
Benefits of Joomla
Key advantages
Trying to convince someone to use Joomla in 2026 feels like recommending Internet Explorer. But hey, if you must use it, there are a few redeeming qualities. Joomla does have some genuinely solid features. Native multilingual support without plugins is impressive. Its permission system is more detailed than most enterprise platforms, and the modular structure gives developers a lot of freedom to architect complex, multi-section sites. If you've got a big team with lots of editors and need granular control, Joomla won't fall apart on you.
If you’re absolutely set on Joomla (and we can’t stop you), we’ll point you toward an agency that still proudly builds 2008-core-web-vital-failing templates. Or you can talk to us, and we’ll at least make sure you don’t regret every step of the journey.
Native multilingual support
Joomla ships with multilingual features baked in, so you don’t need a plugin graveyard just to run a site in five languages. It handles translations cleanly and is genuinely one of the few CMSs that gets this right out of the box.
Granular user permission system
Its ACL system is its biggest bragging right. You can lock down roles, workflows, and access rules with a level of control that most CMS platforms still envy.
Custom field capabilities
Joomla gives you solid flexibility with custom fields, letting you shape structured content without hacking together a dozen extensions. It’s powerful enough for complex layouts and multi-section content.
Active developer community
The community isn’t massive, but the people who are there are dedicated, technical, and still shipping useful extensions and documentation. If you're deep in Joomla land, it’s a lifeline.
Strong security foundation
When properly maintained, Joomla is known for being stable and secure. Regular updates and a security-focused core give it an edge over many older open-source CMS setups.
Modular architecture flexibility
Its module-based layout system lets you build multi-section portals, dashboards, and content-heavy sites without bending the platform backward. If you know what you're doing, it’s flexible enough to scale.
Common questions
Kentico to Joomla migration FAQs
Answers to the most common questions about Kentico to Joomla migration
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.
How much does it cost to migrate from Joomla to a modern CMS?
For a typical Joomla site with 500 to 2,000 pages, expect $15,000 to $60,000 depending on complexity. The content extraction itself is manageable since Joomla uses MySQL, but the real cost is rebuilding custom extensions, templates, and workflows in a modern stack. Most Joomla sites have accumulated years of plugins that need equivalents or replacements. We've found the migration typically pays for itself within 12 months through reduced hosting costs, faster page loads, and eliminated maintenance overhead from outdated PHP dependencies.
How long does a Joomla migration take?
Plan for 6 to 12 weeks for a full migration. Content extraction from Joomla's MySQL database takes a few days. The bulk of the timeline goes toward rebuilding your frontend, replacing extension functionality, and migrating SEO equity (URLs, redirects, metadata). Joomla's version upgrade issues actually work in your favour here. If upgrading between Joomla versions already means a near-rebuild, you might as well migrate to a platform that won't put you through the same pain again in 3 years. We handle the full process including 301 redirect mapping so you don't lose search rankings.
Why are companies finally leaving Joomla?
Performance and developer availability. Joomla sites on shared hosting consistently score poorly on Core Web Vitals, which directly hurts search rankings. Finding developers who still want to work with Joomla's older PHP conventions is getting harder and more expensive every year. The extension ecosystem is shrinking as maintainers move on to other platforms. Companies that delayed migration are now facing a compounding problem where the longer they wait, the fewer resources exist to help them. High cost-per-click on "Joomla migration" search terms tells you everything about how urgently companies want out.
