In the course of regular software updates, the TYPO3 version of the tum.de website was updated from 8 to 10. This happened completely without any unplanned downtime for the editorial team or visitors.
Despite a quick and uncomplicated update, our university team has removed many legacy issues and technical debts in this context. This also allows simple and budget-friendly updates in the future.
By the way: The different TUM websites consist not only of one TYPO3 instance for the central website, but also of a large number of different instances on different servers. Divided into different departments and sub-areas, this encapsulation ensures maximum security and performance.
