TYPO3 v11 LTS reached end-of-life on October 31, 2024. TYPO3 v12 LTS reaches end-of-life in October 2026. TYPO3 v13 LTS will reach end-of-life in December 2027. Every 18 months, a new version ends support, every upgrade breaks extensions and templates, and every cycle costs the same developer budget all over again. That treadmill only stops when you get off it.
What End-of-Life Means for TYPO3 Sites
TYPO3 follows a structured release cycle that is, in principle, predictable. A new Long-Term Support version is released approximately every 18 months. Each LTS version receives three years of free community support covering security patches and bug fixes. After that, the Borchert GmbH / TYPO3 GmbH ELTS program offers up to four additional years of paid extended support for organizations that cannot upgrade immediately.
In practice this creates a treadmill. TYPO3 v11 LTS, which was the current stable version until April 2023, received security support until October 31, 2024. That date passed. Organizations still running v11 are now on ELTS (paid) support or running without patches. TYPO3 v12 LTS is currently the supported free version, but it reaches end-of-life in October 2026. TYPO3 v13 LTS, released in October 2024, is the most current version and receives support until December 2027.
The pattern is the same at every version. The version you are on reaches end-of-life. You must either pay for ELTS, upgrade to the next major version, or run without security patches. If you upgrade, you pay for the upgrade and start the cycle again in 18 months.
What Each TYPO3 Major Upgrade Actually Costs
A TYPO3 major version upgrade is not a software update in the ordinary sense. It is a significant development project. Each major release introduces breaking changes to extension compatibility, TypoScript configuration structure, Fluid template syntax, and database APIs. An organization moving from TYPO3 v10 to v12 cannot simply apply an update package. The upgrade requires a developer who understands both the source version and the target version to audit every installed extension for compatibility, update or replace any extensions without v12-compatible versions, review and update TypoScript configuration for deprecated objects and parameters, update Fluid template syntax for any deprecated ViewHelpers, test the entire site on a staging environment, and resolve any rendering issues before go-live.
For a site with a standard set of extensions and a well-maintained codebase, a major version upgrade typically takes a competent TYPO3 developer one to three weeks. For a site that accumulated technical debt over several versions, or that relies on extensions that were not maintained for the target version, the work can extend significantly. An organization with limited in-house TYPO3 expertise will pay agency rates for this work, on a schedule determined by the TYPO3 release cycle, not by the business.
TYPO3 has a different problem. The platform is technically capable, but the developer community outside German-speaking markets is thin. Long-term maintenance becomes a single-vendor dependency, and the upgrade path between major versions is famously painful.

The Developer Dependency That Never Resolves
The TYPO3 developer pool is concentrated in German-speaking markets. Outside DACH (Germany, Austria, Switzerland), finding a developer with current TYPO3 expertise is a specialist search. The talent pool for TYPO3 maintenance and upgrades has been shrinking as the broader web industry consolidates around platforms with larger ecosystems.
For organizations outside the DACH region, this concentration creates a practical problem: the developers available for TYPO3 work are limited in number, typically command higher rates for specialist knowledge, and may not be available on short notice when a security vulnerability requires urgent attention. Many organizations find themselves in a single-vendor relationship with one agency or one developer who knows their specific TYPO3 implementation. If that relationship ends for any reason, the institutional knowledge of how the site is configured leaves with it.
WordPress does not have this problem. The global WordPress developer community is orders of magnitude larger. Finding a developer to maintain, extend, or update a WordPress site is a commodity search in most markets. The single-vendor dependency that traps many TYPO3 organizations does not exist in the same form.
Why Migrating to WordPress Ends the Cycle
A migration from TYPO3 to WordPress is a one-time investment that ends the upgrade treadmill. WordPress core follows a different versioning model: backwards compatibility is maintained across minor releases, and major functionality changes happen through a plugin ecosystem rather than breaking the core. Organizations that migrated from TYPO3 to WordPress several years ago are still running the same WordPress installation without the recurring forced-upgrade cost that TYPO3 creates.
WordPress now powers over 43% of all websites on the internet. The platform has over 60,000 plugins in the official repository and a global developer community. The content team can publish pages, manage media, and configure navigation without opening a developer ticket. Routine maintenance does not require a TYPO3 specialist. Security updates are applied from the dashboard, not through a development project.
What a Proper TYPO3 to WordPress Migration Covers
TYPO3 stores content in a page tree structure with content elements attached to each page. A proper migration by gConverter reads the TYPO3 database directly: every page from the pages table preserving the parent-child tree structure, every content element from tt_content mapped to the corresponding Gutenberg block, all news records from tx_news_domain_model_news migrated to WordPress posts, all files from the File Abstraction Layer (sys_file and sys_file_reference) imported to the WordPress Media Library, all frontend user accounts from fe_users imported with role mapping, and all URL slugs preserved or 301 redirected so no search ranking is lost in the transition.
The TYPO3 theme, built on TypoScript and Fluid templates, cannot be ported to WordPress. It is rebuilt as a custom WordPress PHP theme that replicates the visual output of the original TYPO3 site exactly. For the full technical breakdown: Why Businesses Are Moving From TYPO3 to WordPress →
How gConverter Handles Your Data
A TYPO3 database contains the personal data of every registered frontend user, every form submission from extensions like Powermail or EXT:form, and any business data stored in custom extension tables. Before any access to your database, gConverter signs a Data Processing Agreement. Credentials are stored in AES-256 encrypted vaults, transmitted over TLS 1.3, and deleted within 24 hours of project completion.

What Clients Say
Went FAR above and beyond to help us work through this project. We are thrilled with the final result and they were professional, great to work with, and responsive every step of the way. Would highly recommend.

Very few conversion issues on the first pass, and they cleaned it right. Very Impressive.

The Bottom Line
TYPO3 v11 is end-of-life. v12 reaches end-of-life in October 2026. v13 in December 2027. The upgrade treadmill is not a one-time cost. It is a recurring expenditure baked into the structure of the platform, payable every 18 months, requiring specialist knowledge that is increasingly concentrated in a shrinking pool of DACH-focused developers.
Every organization running TYPO3 will face the same decision at the next EOL date: pay for ELTS, fund another major upgrade, or migrate to a platform where that cycle does not exist. The organizations that migrated to WordPress several cycles ago are no longer asking this question.
