Since there is no fix version that you migrate from and to, it would mean several different guides. At this moment everything you need is described in the release notes. If you start with the version one above your current and read through to the one you want to upgrade to, you should have all relevant information regarding breaking changes.
There are also upgraded guides in the documentation, e.g. for appsettings.json here detailing pre 2025.11 and post 2025.11 setup or in the setup guides, e.g. here.
