Though there are ways of increasing the lifespan of your website so it delivers value longer, you always need to know the support cycles of your software. TYPO3 CMS has clearly defined update and support cycles. The community supports every Long Term Support (LTS) version for three years after release with security and bug fix releases. A new, stable, major version of TYPO3 CMS is released every 18 months. TYPO3 GmbH offers Extended Long Term Support (ELTS).
