The question comes up in meetings with Portuguese clients every week: is it worth migrating from Joomla to WordPress in 2026? The honest answer is “it depends”. Some Joomla projects in Portugal should stay exactly where they are, and in others, postponing the migration costs more.
TL;DR
- Joomla 5 was released on 17 October 2023 and Joomla 4.0 on 17 August 2021, with PHP 7.2 as the minimum requirement: a healthy technical trajectory, but a smaller ecosystem.
- WordPress 6.7 is the current stable line, with the REST API in core since 4.7 (2016) and the block editor since 5.0 (December 2018).
- Approximate global share according to W3Techs: WordPress above 40 percent, Joomla roughly 1.7 to 2 percent of sites that use a CMS.
- The decision to migrate does not rest on market share but on five concrete criteria: the extension ecosystem, talent available in Portugal, the content model, future integrations and the total cost over three years.
- There are four situations in which keeping Joomla is the right technical choice, and this guide describes them plainly.
Why did Portuguese organisations choose Joomla?
To understand the 2026 decision, you have to recognise why so many Portuguese organisations chose Joomla between 2008 and 2016. It was no accident. It was a defensible technical choice in the context of the time.
Cultural, sports and professional associations adopted Joomla because, out of the box, it offered a more sophisticated hierarchical user model than the WordPress of the day. Municipal councils, parish councils and some regional directorates chose Joomla for the same reason: granular permission control, nested sections and categories, and an admin interface closer to the mental model of a “portal” than of a “blog”.
Small businesses, engineering offices and design studios signed up too. The commercial template ecosystem was rich, and the K2 component offered custom content type capabilities that WordPress only matched later, once Custom Post Types and ACF had matured.
There was a cultural reason as well. Local technical communities and events such as JoomlaDay Lisboa built enough critical mass to sustain specialised agencies, trainers and freelancers. Migrating is not only a technical question, it is also a question of who will maintain the system for the next five years.
How have WordPress and Joomla changed since 2018?
The technical picture is different from 2016, and that difference explains much of the migration decision.
On the WordPress side, three changes were structural. First, the REST API entered core in 4.7, released in December 2016, opening the door to decoupled frontends. Second, the block editor (Gutenberg) arrived with 5.0 in December 2018, redefining how authors create content. Third, the 6.x line consolidated Full Site Editing, making it possible to control headers, footers and page templates without PHP files. Version 6.7 is the current stable reference according to the official announcement on wordpress.org/news.
On the Joomla side, the evolution was technically solid but moved at a different pace. Version 4.0, released on 17 August 2021, modernised the base with Bootstrap 5, Web Components and PHP 7.2 as the minimum. Version 5, released on 17 October 2023, kept that course, removing deprecated code and focusing on performance. The problem is not the product. It is the ecosystem.
The number of actively maintained extensions and the size of the global developer community have shrunk steadily. According to W3Techs (read with the caution any market share statistic deserves), WordPress stays above 40 percent of all websites, while Joomla accounts for roughly 1.7 to 2 percent of sites that use a CMS, with a downward trend. It is not the end of Joomla, but it is a signal that directly affects who you can hire in 2027 to maintain the system.
When should you migrate from Joomla to WordPress?
Five criteria. When three or more apply, migration is the rational choice.
Criterion 1: the extension ecosystem is leaving gaps. If more than 30 percent of the extensions installed on the site have not been updated for 18 months, or if the business needs new features that have no mature Joomla equivalent but do have a stable WordPress one, the balance tips towards migration.
Criterion 2: technical talent in Portugal is more available for WordPress. For an organisation that needs to secure continuous maintenance for five years, market depth matters. In 2026 it is easier to hire and replace WordPress talent in Lisbon, Porto, Braga or Coimbra than Joomla talent at the same level of seniority. This is not a criticism of Joomla, it is an observation about the labour market.
Criterion 3: the content model needs to evolve. If the site’s roadmap calls for custom content types, multiple taxonomies, complex editorial workflows with review and scheduling, or integrations with headless and edge computing, WordPress combined with ACF, Meta Box or Pods offers a better documented path.
Criterion 4: future integrations point to WordPress. CRM, marketing automation, generative AI tools, e-commerce platforms and SEO plugin ecosystems now have far more mature native WordPress integrations. For a site that needs to connect to HubSpot, Salesforce, Mailchimp, ActiveCampaign, the ChatGPT API or modern analytics tools, there is less friction on the WordPress side.
Criterion 5: the total cost of ownership over three years is clearly lower. This calculation has to be done honestly. Migrating has a cost. Keeping Joomla has a cost. The question is which is higher over 36 months, adding up extension licences, maintenance hours, training for in-house teams, and the likelihood of a security incident or an incompatibility breakage. When the WordPress total comes out clearly lower, the migration pays for itself.
When is it better to keep Joomla?
This is the section many agencies avoid writing. There are four situations in which we recommend keeping Joomla.
Situation 1: there are critical custom extensions with no viable migration path. If, over a decade, the organisation has invested in bespoke Joomla components that implement specific business rules (member management, federated event calendars, enrolment systems for continuing education), rewriting everything in WordPress may cost more than the future benefit. In that case, the technical recommendation is to keep Joomla up to date and invest in planned maintenance.
Situation 2: the content model is deeply coupled to K2 or to native section and category structures. When the site has tens of thousands of K2 items with custom fields, mapping them to WordPress without loss is a complex project. If the organisation does not have the capacity for that kind of project in the next 12 months, it is better to freeze the migration roadmap and invest in maintaining what exists.
Situation 3: there is no real budget for a quality migration. In our experience, rushed and underpaid migrations are the main cause of SEO disasters in Portugal. Staying on a properly updated Joomla is better than migrating badly to WordPress. If the client cannot allocate budget for an audit, URL mapping, tested migration scripts, manual validation of redirects and a post-launch monitoring period, the responsible recommendation is to postpone.
Situation 4: the site is stable, maintained and legally compliant. If Joomla is on a supported version, the extensions are up to date, the site complies with GDPR, is aligned with WCAG 2.2 AA and the business indicators are positive, there is no urgency. Migration happens when there is a clear business reason, not because of a technical fashion.
What is the concrete Joomla to WordPress migration path?
Once the decision is to migrate, the work is organised into four phases. Skipping them is the fastest way to break a project in production.
Phase 1: audit
The first phase writes no code. It takes inventory. List every installed extension with its version and maintenance status. List every content type (native articles, K2, JReviews, Sobi2, EasyBlog, ChronoForms, RSForm and any custom component). List every active user with their roles and permissions. List every URL indexed in Search Console and Bing Webmaster, with the associated organic traffic volume. Document every form and where it sends its data. Audit the SEO plugins in use (sh404SEF, JoomSEF, Easy Frontend SEO).
This phase produces a document that is the foundation for everything that follows. Without it, the migration moves forward in the dark.
Phase 2: content model mapping
The second phase decides how each Joomla entity translates into WordPress. Do native articles become Posts or Custom Post Types? Do categories become WordPress categories or custom taxonomies? K2 items with custom fields need Custom Post Types with Advanced Custom Fields or Meta Box. Joomla users with custom roles need an equivalent in WordPress capabilities, often via Members or User Role Editor.
This is where you decide what stays, what gets simplified and what gets discontinued. It is also where you discover that some data has no direct equivalent and requires an editorial decision.
Phase 3: migration scripts
The third phase is technical and iterative. Build scripts (PHP via WP-CLI, or tools such as FG Joomla to WordPress) that read from the Joomla database and write to the WordPress database according to the agreed mapping. Each script must be idempotent and tested against a snapshot of the real database, not against a synthetic environment.
Image migration deserves special attention. Absolute paths in Joomla content (/images/stories/…) need to be rewritten to WordPress paths (/wp-content/uploads/…), and the files copied with their metadata preserved where relevant.
Phase 4: SEO and redirects
The fourth phase is where most projects in Portugal fail. Every old URL needs a 301 redirect to its new URL. It is not optional. The typical Joomla structure with sh404SEF (/category/subcategory/article) rarely matches the default WordPress structure. Build an old URL to new URL mapping file, import it into a reliable redirect plugin (Redirection, or server-side rules), and validate 100 percent of the redirects before go-live.
After go-live, resubmit the sitemaps in Google Search Console and Bing Webmaster, monitor 404 errors daily for the first four weeks, and add any missing redirects. Expecting organic traffic to fluctuate during the first four to eight weeks is normal. A permanent loss is a sign of incomplete mapping.
What are the most common Joomla migration problems?
Five pitfalls we see again and again in migration projects in Portugal.
Pitfall 1: extension data with no WordPress equivalent. Components such as JReviews, Sobi2 and some directory components store data in their own tables. No WordPress plugin accepts that import automatically. It takes a custom script, and that means development hours.
Pitfall 2: K2 data. K2 was so popular in Portugal that many migrations stumble here. K2 items, K2 categories, K2 extra fields, K2 authors and K2 tags do not match the native Joomla model, let alone WordPress. Some tools cover the simple case, but not custom fields or multiple relationships. Plan extra time.
Pitfall 3: MultiCategory mapping. In Joomla, an article belongs to one primary category. In WordPress, a post can belong to several categories. If the Joomla site used extensions that simulated multiple categories, deciding how to represent that in WordPress (multiple categories, a custom taxonomy, tags) affects navigation, archives and URLs.
Pitfall 4: URL preservation. Even with 301 redirects, some sites forget specific URL fragments (pagination parameters, internal anchors, static files served by Joomla). The cost shows up as lost traffic six weeks after launch.
Pitfall 5: custom user roles. The Joomla ACL system is more granular than the WordPress capabilities system. Migrating users is not just migrating names and email addresses. It means deciding how each custom role translates and validating that the resulting permissions match what was intended, with no excess privileges and no lost access.
Joomla to WordPress migration service
I handle Joomla to WordPress migrations as an integrated project, not as an isolated task. I work on four fronts in parallel: content architecture (including headless WordPress approaches when the frontend justifies it), performance engineering at the level of Cloudflare Workers and edge computing, legal compliance (GDPR, WCAG and BFSG/EAA, NIS2 and DORA where applicable), and visibility in traditional search engines and in AI-generated answers (GEO).
For projects with modern frontend requirements, there is further technical reading in the headless vs monolithic comparison and in the Next.js vs Astro decision matrix for the presentation layer in 2026. Our approach combines senior engineers with the nearshore philosophy we describe as the WPPoland standard.
There is no fixed price list. Every migration project differs in size and risk, and the estimate is individual, after the audit.
What else to read before migrating from Joomla?
This guide is one node in the cluster on modernising WordPress stacks in Portugal. It connects to the articles on legal compliance in 2026, edge performance with Cloudflare Workers, headless architectures and GEO visibility strategy. For an informed decision, read these articles side by side before making any commitment.
How do you map 301 redirects in a Joomla migration?
Moving a complex database from Joomla to WordPress needs a surgical plan to avoid losing organic traffic:
- Normalising permalink structures: Joomla has historically used category parameters and numeric IDs in URLs, which differ from the clean WordPress taxonomy. Building a complete 301 redirect table at web server level (Nginx or an .htaccess file) ensures that all the authority built up over the years carries over without loss.
- Migrating metadata and user hierarchies: the process must correctly convert authors, access permissions and data from legacy SEO plugins into the new fields used by tools such as Yoast or Rank Math.
- Post-migration checks in Google Search Console: actively monitoring 404 errors during the first four weeks after the migration lets you fix forgotten routes and consolidate the organic authority of the new WordPress site in Portugal.
How do you optimise performance and security after leaving Joomla?
Once the content has moved from Joomla into the WordPress ecosystem, technical consolidation is essential:
- Advanced object and page caching: configuring Redis and an edge CDN layer ensures the new setup delivers very fast response times, improving Core Web Vitals scores straight away.
- Removing legacy code and hardening security: disabling orphaned routes and scripts from the old CMS prevents automated intrusion attempts. The modernised platform also makes day-to-day editorial work easier for the business.
