TL;DR
For TYPO3 maintenance, 2026 comes with clear deadlines: free support for TYPO3 v12 ended on 30 April 2026, v13 LTS is supported until October 2027, and the new v14 LTS was released on 21 April 2026 with support until around April 2029. If you still run v12 or older, you have two options: paid Extended Long Term Support (ELTS) as a bridge, or upgrading to v13 or v14. Without one of the two, your website is left without security updates and becomes a risk.
TYPO3 maintenance in 2026: the support deadlines you need to know
TYPO3 is a widely used enterprise CMS in the German-speaking market, especially among companies, universities and public institutions. Just like a learning platform, safe operations stand and fall with updates and maintenance. TYPO3 follows a clear release plan with long term support (LTS) versions, which makes planning easier but also sets firm deadlines.
As of August 2026: TYPO3 v12 LTS has not received free security updates since 30 April 2026. TYPO3 v13 LTS is the proven production version and is supported until October 2027. TYPO3 v14 LTS was released on 21 April 2026 and receives roughly three years of free security updates until around April 2029. The official dates are published in the TYPO3 roadmap.
What does the end of support for TYPO3 v12 mean?
Once free support expires, newly discovered security issues are no longer fixed in regular releases. The website keeps working at first but becomes more vulnerable with every month. For operators with GDPR duties this is doubly critical, because an avoidable incident on outdated software is hard to justify to supervisory authorities. Technical debt also grows: the longer an upgrade is postponed, the bigger the version jump, the extension effort and the costs.
Option 1: ELTS as a paid bridge
With Extended Long Term Support (ELTS), TYPO3 GmbH offers paid security updates for up to three additional years after regular support ends. For v12, ELTS reaches until 2030. It is a legitimate transitional solution when an upgrade is not immediately possible for budget or project reasons. Important: ELTS buys time, it does not replace the upgrade. Costs continue yearly and the version gap keeps growing.
Option 2: upgrade to TYPO3 v13 or v14
The sustainable route is the upgrade. Coming from v12, you move to v13 LTS or directly to v14 LTS depending on your extension situation. A clean TYPO3 upgrade works like a small migration: an inventory of extensions and customisations, a test environment, an upgrade run with testing of all functions, and only then the switch of the production system. The method matches what we describe for learning platforms in Moodle migration in 6 steps; the approach transfers well.
Ongoing TYPO3 maintenance: more than just updates
Between the big version jumps, TYPO3 needs continuous care: regular core and extension updates, PHP and database maintenance, tested backups, monitoring and security checks. As with every business-critical platform: maintenance is routine, not a project. Organisations without their own TYPO3 team sensibly outsource this routine to a provider with a maintenance contract, analogous to managed hosting for Moodle.
Frequently asked questions about TYPO3 maintenance
Which TYPO3 version should I run in 2026?
For production systems, v13 LTS and v14 LTS are the right choice. New projects sensibly start directly on v14 LTS.
What does ELTS cost?
ELTS is licensed per installation and year with tiered prices. Weigh the cost against the effort of an upgrade; in the medium term the upgrade usually wins.
How long does a TYPO3 upgrade take?
That depends on extensions and custom development. Small sites manage the jump in a few days; complex portals plan several weeks including testing.
Can I skip versions?
Upgrades usually proceed along the LTS versions one after another. Your service provider determines the best path for your installation.
Conclusion
The deadlines are clear: v12 can no longer be run safely without ELTS, v13 carries you until October 2027, and v14 LTS is the future until at least 2029. If you plan now, you decide the timing and budget yourself instead of reacting under pressure later.
Next steps
Determine which TYPO3 version you are currently running and which extensions affect an upgrade. Then make a conscious choice between ELTS as a bridge and the direct upgrade.
