In Octobre 2021, TYPO3 released version 11.5 LTS. Support for version 9.5 expired almost simultaneously. This increased the risk of a security vulnerability for websites running TYPO3 Version 9.5 or older. An update is strongly recommended.
An update or upgrade to the latest version TYPO3 11.5 LTS is most sensible to facilitate long-term and effective investment. However, the updates of individual extensions to TYPO3 11.5 are very extensive, depending on their status and function. Budgets can run very high especially when an upgrade over several TYPO3 versions is necessary.
TYPO3 offers extended long-term support to keep you one the safe side. Further information can be found at https://typo3.com/products/extended-support/.Annual fees are approx. 2600 EUR per web page. An exact calculation can be made at https://typo3.com/ordering.
Extended Support of TYPO3 ELTS provides only a temporary solution. We recommend a website with the latest TYPO3 version for the long run.
Our tip: Should the cost of the update/upgrade to TYPO3 11.5 be particularly high, we recommend a medium-term planned upgrade including a visual relaunch of the website or a completely new website. In some cases, the new development of a website can be even less complex than the implementation of the necessary adjustments. In addition, an optical relaunch also shows website visitors that new investment has been made. An update to TYPO3 11.5 alone is (unfortunately) not visible from the outside. TYPO3 long-term support provides you extra confidence and safety.
We would be happy to have a look at your TYPO3 website and plan your individual upgrade to a secure and modern online presence.
