How to update 3.6.5 Plainkit to 3.10?

Hello, I have a Kirby 3.6.5 website that I created with Plainkit. Now I need to migrate to 3.10 because the PHP version is outdated, but I don’t know how. (The website is already down…)

The instructions say to copy the “Kirby” folder, but when I download the ZIP file for version 3.10 ( Release 3.10.0 · getkirby/kirby · GitHub ), I can’t find a “Kirby” folder. So how do I proceed?

Sorry if I’ve overlooked something, I haven’t found anything in the forum so far…

When you unzip the download, you get a folder called kirby-3.10.2 which you rename to kirby and then replace the kirby folder in your current project with that folder.
