If you're still running a Joomla 3 site in 2025, you already know something's wrong. Maybe your developer ghosted you. Maybe the quotes you've gotten for an upgrade made your eyes water. Or maybe you've been reading forum posts about migrating to Joomla 4, then Joomla 5, and now Joomla 6 — and you're wondering if this upgrade treadmill ever actually stops.

I've migrated dozens of Joomla sites over the years, some to newer Joomla versions and many to entirely different platforms. I'm going to be honest with you about what the Joomla upgrade path actually looks like in 2025, what it costs, and whether it's even worth doing. Because for a lot of site owners, the answer isn't what the Joomla community wants to hear.

Joomla 3 End of Life: The Joomla 6 Upgrade Trap Nobody Warns You About

The Joomla 3 End of Life Timeline

Let's get the facts straight. Joomla 3's end of life wasn't a surprise — it was announced years in advance:

  • August 2023: Joomla 3 officially reached end of life. No more security patches. No more bug fixes. Nothing.
  • Joomla 4: Released in August 2021, it was supposed to be the migration target. It reached end of life in October 2025.
  • Joomla 5: Released in October 2023, this is the current stable version with support until 2027.
  • Joomla 6: Expected in late 2025 or early 2026, with Joomla 5 and 6 sharing a brief overlap period.

Here's the part that trips people up: Joomla 4 is already end of life too. If you were putting off your Joomla 3 migration thinking you'd go to Joomla 4, that ship has sailed. You now need to target Joomla 5 at minimum, or wait for Joomla 6. And the migration from Joomla 3 to Joomla 5 is not a simple update — it's essentially a rebuild.

Why You Can't Just Click Upgrade

If you're coming from WordPress, you might think CMS upgrades are like clicking a button. Joomla major version upgrades have never worked that way, and the 3-to-5 jump is particularly painful.

The Extension Problem

Joomla 3 ran on a completely different extension architecture. The framework changed significantly in Joomla 4, with the adoption of namespaces, a new MVC structure, and the removal of legacy APIs. Many popular Joomla 3 extensions were:

  • Abandoned entirely — the developers moved on or went out of business
  • Rewritten as paid upgrades — you'll need to buy new licenses
  • Replaced by different extensions — requiring manual data migration

I've seen sites running 15-20 third-party extensions on Joomla 3. In a typical migration, maybe 40-60% of those extensions have a Joomla 5 equivalent. The rest? You're either finding alternatives, building custom replacements, or cutting features.

The Template Problem

Joomla 3 templates don't work on Joomla 5. Period. Your template was probably built on the Bootstrap 2 framework that Joomla 3 shipped with. Joomla 5 uses Bootstrap 5. The template override system changed. The module position naming conventions shifted. Your entire front-end needs to be rebuilt or replaced.

If you bought a commercial template from providers like JoomlArt, GavickPro, or Shape5, check whether they've released a Joomla 5 version. Some have. Many haven't. And even if they have, it won't look identical — you'll need to reconfigure everything.

The Database Migration

Joomla does provide a migration path through their built-in update component, but it requires stepping through versions: 3 → 4 → 5. You can't skip Joomla 4. Each step has its own set of pre-update checks and potential failures. Database schema changes between major versions mean you need clean data with no corruption, and if you've been running Joomla 3 for years with various extensions installed and uninstalled, your database probably has orphaned tables and inconsistencies.

The Real Cost of Migrating Joomla 3 to Joomla 5 or 6

Let me give you real numbers based on what I've seen in 2024-2025:

Site Complexity Extension Count Estimated Migration Cost Timeline
Simple brochure site (5-15 pages) 0-5 $2,000 - $5,000 2-4 weeks
Small business site with blog 5-10 $5,000 - $12,000 4-8 weeks
E-commerce or membership site 10-20 $12,000 - $30,000 8-16 weeks
Large portal with custom extensions 20+ $30,000 - $75,000+ 16-32 weeks

These numbers reflect the full scope: template rebuild, extension migration, data migration, testing, and deployment. They don't include content cleanup or SEO redirect mapping, which can add 20-30% to the total.

Here's the question nobody asks enough: does it make sense to spend $15,000 migrating a Joomla 3 site to Joomla 5 when you could build something better for the same money?

Security Risks of Staying on Joomla 3

I need to be blunt here. Running Joomla 3 in 2025 is a serious security liability.

Since end of life in August 2023, there have been multiple vulnerabilities discovered in Joomla's codebase that were patched in Joomla 4/5 but will never be patched in Joomla 3. These include:

  • SQL injection vulnerabilities in core components
  • Cross-site scripting (XSS) vectors in the admin panel
  • Authentication bypass issues in the API layer
  • PHP compatibility problems — Joomla 3 doesn't support PHP 8.2+, and hosting providers are dropping PHP 8.0 and 8.1 support

The PHP issue is the most pressing practical concern. Many shared hosting providers have already deprecated PHP 8.0, and PHP 8.1's security support ended in December 2025. If your host forces a PHP upgrade, your Joomla 3 site may simply break.

If you absolutely must stay on Joomla 3 temporarily while planning a migration, here's the minimum you should do:

# .htaccess hardening for Joomla 3
# Block direct access to sensitive files
<FilesMatch "(configuration\.php|htaccess\.txt|web\.config\.txt|README\.txt|LICENSE\.txt)">
  Require all denied
</FilesMatch>

# Disable directory listing
Options -Indexes

# Block common exploit attempts
RewriteEngine On
RewriteCond %{QUERY_STRING} (eval\(|base64_decode|fromCharCode|alert\() [NC,OR]
RewriteCond %{QUERY_STRING} (<|%3C).*script.*(>|%3E) [NC,OR]
RewriteCond %{QUERY_STRING} (GLOBALS|_REQUEST|_GET|_POST)\[.*\] [NC]
RewriteRule .* - [F,L]

But this is a band-aid. Not a solution.

The Joomla 6 Situation: What's Coming

Joomla follows an odd-even release strategy now. Even-numbered releases (4, 6) are "development" milestones that overlap with the previous odd release. Odd-numbered releases (5, 7) are the long-term targets.

Joomla 6 is expected to bring:

  • Improved media manager with better asset handling
  • Enhanced workflow system for content approval
  • Better API support for headless usage
  • Potential Symfony 7 components under the hood

But here's the trap: Joomla 6 will have a shorter support window than Joomla 5. It's designed as a stepping stone to Joomla 7, which will be the next long-term release. If you migrate to Joomla 6, you'll need to migrate again to Joomla 7 within a couple of years.

The Joomla project's release cadence means you're committing to periodic major upgrades every 2-3 years. Each one carries risk and cost. For a business that just wants a website that works, this cadence is exhausting.

Honest Comparison: Upgrade vs. Migration to a Modern Stack

Let me lay this out as fairly as I can:

Factor Joomla 5/6 Upgrade Headless CMS + Modern Frontend WordPress Migration
Upfront cost $5K-$75K $8K-$50K $3K-$25K
Annual maintenance $2K-$8K $1K-$4K $2K-$6K
Performance (TTFB) 200-800ms 50-150ms 150-600ms
Security surface area Medium-High Low Medium-High
Content editor experience Joomla admin (dated) Modern CMS UI Block editor
Future upgrade burden High (every 2-3 years) Low (decoupled) Medium
Developer availability Shrinking pool Growing pool Large pool
SEO migration complexity Low (same URL structure) Medium (redirect mapping) Medium

The developer availability column deserves extra attention. The Joomla developer community has been shrinking for years. Finding a qualified Joomla developer in 2025 is harder and more expensive than it was in 2020. Stack Overflow's 2024 developer survey showed Joomla usage at less than 1% among professional developers, compared to its peak years.

The Headless CMS Option

If your Joomla site is primarily a content site — articles, pages, maybe a blog — a headless CMS approach with a framework like Next.js or Astro can give you dramatically better performance, lower ongoing maintenance, and a better editing experience.

A headless CMS setup decouples your content from your presentation layer. Your editors work in something like Sanity, Storyblok, or Payload CMS, and the frontend is built as a static or server-rendered site. There's no monolithic CMS to keep updated. No plugin vulnerabilities to worry about.

The initial build cost is comparable to a Joomla migration for medium-complexity sites, but the total cost of ownership over 5 years is typically 30-50% lower because you're not dealing with the CMS upgrade treadmill.

The WordPress Option

I know, I know. Going from one monolithic CMS to another feels like trading one set of problems for a different set. And it is. WordPress has its own security challenges and update burden.

But WordPress has one overwhelming advantage: ecosystem size. You'll never struggle to find a developer. Hosting options are everywhere. And if you eventually want to go headless with WordPress as the backend, that path exists too.

For simple brochure sites, WordPress with a well-maintained theme can be the fastest and cheapest migration from Joomla 3. Just go in with your eyes open about ongoing maintenance.

When Upgrading Joomla Actually Makes Sense

I'm not going to tell you Joomla is dead. It isn't. There are legitimate cases where staying on Joomla is the right call:

  1. You have heavy custom extension development — If your site runs on custom-built Joomla components that represent significant business logic, rewriting those for a different platform may cost more than upgrading them for Joomla 5.

  2. Your team knows Joomla deeply — If you have in-house developers who maintain the site and they're fluent in Joomla's architecture, the migration to Joomla 5 is a known quantity for them.

  3. Multi-language sites using Joomla's native system — Joomla's built-in multilingual support is genuinely good and doesn't require plugins. If you're running a 10-language site, replicating that elsewhere has real costs.

  4. ACL-heavy sites — Joomla's Access Control List system is more granular than WordPress out of the box. If your site relies heavily on user groups and viewing levels, that's non-trivial to replicate.

  5. You're already on Joomla 4 — The 4 to 5 upgrade is much smoother than 3 to 5. Most extensions that work on Joomla 4 work on Joomla 5 with minimal changes.

When You Should Leave Joomla Entirely

Here's where I get real with you. For the majority of Joomla 3 site owners — especially small to medium businesses — migrating away from Joomla is the better long-term investment. Specifically:

  • Your site is primarily a marketing/brochure site — You don't need a CMS with Joomla's complexity. A modern static site generator or even a simple WordPress build will serve you better.

  • You're paying a developer retainer just to keep the lights on — Joomla's maintenance overhead is higher than most alternatives.

  • Your site is slow — Joomla 3 sites are typically running on shared hosting with heavy templates. Modern frameworks can deliver your content in a fraction of the time.

  • You can't find your developer — If the person who built your Joomla site is gone and nobody else wants to touch it, that's a clear signal.

  • Mobile performance is poor — Many Joomla 3 templates were built in the early responsive era. They technically work on mobile but they're bloated.

The Migration Process: Step by Step

Regardless of which direction you choose, here's the practical process:

Step 1: Audit Everything

Before you touch anything, document what you have:

# Export a list of all Joomla extensions
# Run this query against your Joomla database
SELECT name, type, element, enabled 
FROM #__extensions 
WHERE type IN ('component', 'module', 'plugin', 'template') 
AND (package_id = 0 OR package_id IS NULL)
ORDER BY type, name;

Also document:

  • Total number of articles/content items
  • Menu structure and URL patterns
  • User accounts and access levels
  • Custom form submissions and data
  • Third-party integrations (payment gateways, email services, etc.)
  • Current hosting environment (PHP version, MySQL version)

Step 2: Map Your URLs

This is the most commonly botched part of any CMS migration. Every URL on your current site that has any search engine value needs to redirect to its equivalent on the new site.

# Example Joomla to new platform redirect map
Redirect 301 /index.php/about-us /about
Redirect 301 /index.php/services/web-design /services/web-design
Redirect 301 /index.php/blog/123-article-title /blog/article-title

Use Screaming Frog or Sitebulb to crawl your existing site and export all URLs. Cross-reference with Google Search Console to identify which pages actually receive organic traffic. Those are your priority redirects.

Step 3: Extract Your Content

Joomla stores content in the #__content table. You can export this as CSV or JSON for import into whatever platform you're targeting:

SELECT 
  c.id,
  c.title,
  c.alias,
  c.introtext,
  c.fulltext,
  c.state,
  c.catid,
  cat.title AS category_title,
  c.created,
  c.modified,
  c.metadesc,
  c.metakey
FROM #__content c
LEFT JOIN #__categories cat ON c.catid = cat.id
WHERE c.state = 1
ORDER BY c.created DESC;

Step 4: Build and Test

Build the new site in a staging environment. Test every page, every form, every integration. Run Lighthouse audits. Check mobile rendering. Verify that your redirect map works.

Step 5: Launch and Monitor

After launch, monitor Google Search Console daily for the first two weeks. Watch for 404 errors from missed redirects. Check your organic traffic trends. It's normal to see a temporary dip during a migration, but it should recover within 4-8 weeks if your redirects are solid.

FAQ

Is Joomla 3 still safe to use in 2025? No. Joomla 3 reached end of life in August 2023 and no longer receives security patches. Multiple unpatched vulnerabilities exist in the wild. If you're running Joomla 3, you're running on borrowed time. Your site is a target for automated attacks that specifically scan for known Joomla 3 vulnerabilities.

Can I upgrade directly from Joomla 3 to Joomla 5? Not directly through the built-in updater. You need to go from Joomla 3 to Joomla 4 first, then from Joomla 4 to Joomla 5. Each step requires passing pre-update checks and potentially fixing compatibility issues. Some developers use direct database migration approaches that skip the stepped upgrade, but this requires deep technical expertise.

How much does it cost to migrate a Joomla 3 site? For a simple brochure site, expect $2,000-$5,000 whether you're upgrading within Joomla or moving to another platform. Business sites with e-commerce, membership features, or custom components typically run $12,000-$30,000+. The biggest cost drivers are custom extension rewrites and template rebuilds.

Should I wait for Joomla 6 before migrating? No. Joomla 6 will have a shorter support window than Joomla 5 and is designed as a transition release to Joomla 7. If you're going to stay in the Joomla ecosystem, target Joomla 5 now. Waiting exposes you to additional months of security risk with no meaningful benefit.

Will my Joomla 3 extensions work on Joomla 5? Almost certainly not without updates. Joomla 4 introduced major architectural changes including new namespacing, an updated MVC pattern, and removal of legacy APIs. Many Joomla 3 extensions have been abandoned entirely. Check the Joomla Extensions Directory for Joomla 5 compatibility before planning your migration.

Is Joomla still worth using in 2025? Joomla still has strengths — particularly its native multilingual support and granular access control. But its market share has declined to under 2% of CMS-powered websites, and the developer community is shrinking. For new projects, most developers recommend WordPress, headless CMS platforms, or modern frameworks. For existing Joomla sites with significant custom development, upgrading within Joomla can still make sense.

What's the best alternative to Joomla for a business website? It depends on your needs. For simple marketing sites, a headless CMS with a static frontend (Astro or Next.js) gives you the best performance and lowest maintenance burden. For sites that need frequent content updates by non-technical editors, WordPress or a modern headless CMS like Sanity or Payload provides a better editing experience. For complex web applications, a custom build on Next.js with a headless backend is typically the strongest long-term choice.

How do I preserve my SEO rankings during a Joomla migration? Three things matter most: proper 301 redirects from every old URL to its new equivalent, maintaining your content quality and keyword targeting, and keeping your site structure reasonably similar. Use Google Search Console to identify your highest-traffic pages and prioritize those in your redirect mapping. Expect a temporary ranking fluctuation for 4-8 weeks after migration — this is normal and recoverable if your redirects are properly implemented.
