Hello, I´ve tried to find some information in koha´s documentation, but I failed to find anything usable. Sorry for my question: Does Koha have a common way (script?) to update it to newer versions or do I have to make a new installation of it, configure it and reinstall the previous dumped database? BTW: I´ve just tried to install the version 2020.11 on a new raspberry pi 4. It works with the normal procedure without any hassle. I want to use this as a test system only. The SD cards may be restored very easy, if I´ve made some silly things with Koha on it. Nice, good work!
