Genau wie bei einer Lernplattform gilt: Der sichere Betrieb steht und f\u00e4llt mit Updates und Wartung. TYPO3 folgt dabei einem klaren Versionsplan mit Long Term Support (LTS), der die Planung erleichtert, aber auch verbindliche Fristen setzt.<\/p><p>Stand August 2026 gilt: <strong>TYPO3 v12 LTS<\/strong> erh\u00e4lt seit dem 30. April 2026 keine kostenlosen Sicherheitsupdates mehr. <strong>TYPO3 v13 LTS<\/strong> ist die bew\u00e4hrte Produktivversion und wird bis Oktober 2027 unterst\u00fctzt. <strong>TYPO3 v14 LTS<\/strong> erschien am 21. April 2026 und erh\u00e4lt rund drei Jahre kostenlose Sicherheitsupdates bis etwa April 2029. Die offiziellen Termine ver\u00f6ffentlicht das Projekt in der <a href=\"https:\/\/typo3.com\/typo3-cms\/development-roadmap\/maintenance-releases\" target=\"_blank\" rel=\"noopener\">TYPO3 Roadmap<\/a>.<\/p><h2 id=\"heading-1\">Was bedeutet das Support-Ende von TYPO3 v12?<\/h2><p>L\u00e4uft der kostenlose Support aus, werden bekannt gewordene Sicherheitsl\u00fccken nicht mehr im Rahmen der regul\u00e4ren Releases geschlossen. Die Website funktioniert zun\u00e4chst weiter, wird aber mit jedem Monat angreifbarer. F\u00fcr Betreiber mit DSGVO-Pflichten ist das doppelt kritisch, denn ein vermeidbarer Vorfall auf veralteter Software l\u00e4sst sich gegen\u00fcber Aufsichtsbeh\u00f6rden kaum rechtfertigen. Zus\u00e4tzlich wachsen die technischen Altlasten: Je l\u00e4nger ein Upgrade aufgeschoben wird, desto gr\u00f6\u00dfer werden Versionssprung, Extension-Aufwand und Kosten.<\/p><h2 id=\"heading-2\">Option 1: ELTS als bezahlte \u00dcbergangsl\u00f6sung<\/h2><p>Mit Extended Long Term Support (ELTS) bietet die TYPO3 GmbH kostenpflichtige Sicherheitsupdates f\u00fcr bis zu drei weitere Jahre nach dem regul\u00e4ren Support-Ende. F\u00fcr v12 reicht ELTS damit bis 2030. Das ist eine seri\u00f6se \u00dcbergangsl\u00f6sung, wenn ein Upgrade aus Budget- oder Projektgr\u00fcnden nicht sofort m\u00f6glich ist. Wichtig: ELTS kauft Zeit, ersetzt aber das Upgrade nicht. Die Kosten laufen j\u00e4hrlich weiter und der Versionsabstand w\u00e4chst.<\/p><h2 id=\"heading-3\">Option 2: Upgrade auf TYPO3 v13 oder v14<\/h2><p>Der nachhaltige Weg ist das Upgrade. Wer von v12 kommt, springt je nach Extension-Lage auf v13 LTS oder direkt auf v14 LTS. Ein sauberes TYPO3 Upgrade l\u00e4uft wie eine kleine Migration: Bestandsaufnahme von Extensions und Anpassungen, Aufbau einer Testumgebung, Upgrade-Durchlauf mit Pr\u00fcfung aller Funktionen und erst dann der Wechsel des Produktivsystems. Das Vorgehen entspricht dem, was wir f\u00fcr Lernplattformen im Beitrag <a href=\"https:\/\/www.learnteq.de\/en\/moodle-migration-in-6-steps-safely-and-without-data-loss\/\">Moodle Migration in 6 Schritten<\/a> beschreiben, die Methodik ist \u00fcbertragbar.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6e96372 elementor-widget elementor-widget-button\" data-id=\"6e96372\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm elementor-animation-grow\" href=\"https:\/\/www.learnteq.de\/en\/contact\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Request TYPO3 advice<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3db256f elementor-widget elementor-widget-text-editor\" data-id=\"3db256f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2 id=\"heading-4\">Laufende TYPO3 Wartung: mehr als nur Updates<\/h2><p>Auch zwischen den gro\u00dfen Versionsspr\u00fcngen braucht TYPO3 kontinuierliche Pflege: regelm\u00e4\u00dfige Core- und Extension-Updates, PHP- und Datenbankpflege, getestete Backups, Monitoring und Sicherheits-Checks. Wie bei jeder gesch\u00e4ftskritischen Plattform gilt: Wartung ist Routine, kein Projekt. Organisationen ohne eigenes TYPO3-Team lagern diese Routine sinnvollerweise an einen Dienstleister mit Wartungsvertrag aus, analog zum <a href=\"https:\/\/www.learnteq.de\/en\/managed-moodle-hosting-advantages-services-and-costs-at-a-glance\/\">Managed Hosting bei Moodle<\/a>.<\/p><h2 id=\"heading-5\">H\u00e4ufige Fragen zur TYPO3 Wartung<\/h2><p><strong>Welche TYPO3 Version sollte ich 2026 einsetzen?<\/strong><br \/>F\u00fcr Produktivsysteme sind v13 LTS und v14 LTS die richtige Wahl. Neue Projekte starten sinnvollerweise direkt auf v14 LTS.<\/p><p><strong>Was kostet ELTS?<\/strong><br \/>ELTS wird j\u00e4hrlich pro Installation lizenziert, die Preise sind gestaffelt. Rechnen Sie die Kosten gegen den Aufwand eines Upgrades, meist gewinnt mittelfristig das Upgrade.<\/p><p><strong>Wie lange dauert ein TYPO3 Upgrade?<\/strong><br \/>Das h\u00e4ngt von Extensions und Eigenentwicklungen ab. Kleine Sites schaffen den Sprung in wenigen Tagen, komplexe Portale planen mehrere Wochen inklusive Tests.<\/p><p><strong>Kann ich Versionen \u00fcberspringen?<\/strong><br \/>Upgrades erfolgen \u00fcblicherweise entlang der LTS-Versionen nacheinander. Ihr Dienstleister pr\u00fcft den besten Pfad f\u00fcr Ihre Installation.<\/p><h2 id=\"heading-6\">Fazit<\/h2><p>Die Fristen sind eindeutig: v12 ist ohne ELTS nicht mehr sicher zu betreiben, v13 tr\u00e4gt bis Oktober 2027 und v14 LTS ist die Zukunft bis mindestens 2029. Wer jetzt plant, entscheidet selbst \u00fcber Zeitpunkt und Budget, statt sp\u00e4ter unter Druck reagieren zu m\u00fcssen.<\/p><h2 id=\"heading-7\">Weitere Schritte<\/h2><p>Stellen Sie fest, welche TYPO3 Version Sie aktuell betreiben und welche Extensions ein Upgrade beeinflussen. Entscheiden Sie dann bewusst zwischen ELTS als \u00dcbergang und dem direkten Upgrade.<\/p><p>Sie brauchen Unterst\u00fctzung bei Upgrade oder laufender Wartung?
