Guides for specific software problems · TYPO3 end of support
Your TYPO3 12 no longer gets security updates — and your agency has no time?
Free support for TYPO3 v12 LTS ended on 30 April 2026. Since then, security updates are only available through the paid ELTS programme. On 31 December 2026, security support for PHP 8.2 ends as well, and hosting providers are retiring old PHP versions. For many companies both arrive at once: the website has to be worked on now — and the agency that built it has closed, is fully booked or sends a quote nobody expected.
Does this sound familiar?
- The TYPO3 backend warns that your version is no longer supported.
- Your hosting provider announces it will switch off PHP 8.1 or 8.2.
- The agency that built the website doesn't reply or has no capacity.
- The upgrade quote runs to five figures, and you can't tell whether that's reasonable.
- Some extensions in your system haven't been maintained for years.
Why this happens
TYPO3 has fixed support periods
Each LTS version gets about three years of free updates. TYPO3 v12 came out in April 2023; since May 2026 security fixes are only available for a fee (ELTS).
PHP ages at the same time
TYPO3 runs on PHP. PHP 8.1 has had no security updates since January 2026, and PHP 8.2 won't from January 2027. Hosting providers follow, often at short notice.
Extensions are the real risk
The TYPO3 core upgrades well. The effort lies in third-party extensions and custom code that nobody has touched for years.
Agencies prioritise new projects
Upgrading old or someone else's code is unattractive for many agencies. Their quotes reflect that — or never arrive.
What to do now
-
1
Check the version and PHP
The TYPO3 backend shows the version under "About TYPO3"; the Install Tool shows the PHP version under "Environment". Ask your hosting provider how long they will keep running your PHP version.
-
2
List the extensions
Which extensions are installed, and which already exist for v13 or v14? That decides the effort more than anything else.
-
3
Choose your route
Upgrade to v13 (security updates until the end of 2027) or straight to v14 (until June 2029), use ELTS as a bridge — or rebuild without a CMS if the website rarely changes.
-
4
Never on the live system
Back up the database and files, set up a copy, upgrade and test there. Only then switch over.
-
5
Keep up afterwards
Applying small updates regularly saves most of the work at the next major version jump.
How we help
We have worked with TYPO3 since 2008 and migrated installations from version 6 to 13 — including systems built by others. We take over your TYPO3, bring it to a supported version and keep it up to date afterwards.
- Assessment: version, PHP, extensions, custom code — and an honest estimate of the effort
- Upgrade to v13 or v14, including adapting or replacing outdated extensions
- Takeover even without documentation and without the old agency's help
- Ongoing updates on the Production plan: instructions received by 09:00 Japan time are done the same Japanese business day — while you sleep
- If a rebuild without a CMS is cheaper for you, we'll tell you

Frequently asked questions
Do I have to upgrade right away?
Your website keeps running. But newly found security holes in v12 are only fixed in the paid ELTS. The longer a public website runs without updates, the greater the risk. Plan the upgrade in months, not years.
v13 or straight to v14?
v13 gets security updates until the end of 2027, v14 until June 2029. If your extensions already support v14, going straight there usually pays off — it saves another upgrade next year. We clarify this in the assessment.
What is ELTS, and is it worth it?
ELTS (Extended Long Term Support) is TYPO3 GmbH's paid programme that keeps supplying older versions with security fixes. It's a good bridge if the upgrade can only happen later — but not a substitute for it.
You didn't build our website. Can you still help?
Yes. We regularly take over systems built by other providers, even without documentation. We only need access to the server, the database and the backend.
What does it cost?
The upgrade and ongoing maintenance run on a Production plan: a fixed monthly base fee plus the hours actually worked. You get a first estimate of the effort in the free 15-minute call.
