Migration: Configuration options
In RavenDB 4.0 the configuration settings are defined in settings.json. The file is created when running the server for the first time from the settings.default.json file which is located next to the server binaries and its default content is as follows:
{
"ServerUrl": "http://127.0.0.1:0",
"Setup.Mode": "Initial",
"DataDir": "RavenData"
}
Setup Wizard
The default Setup.Mode: Initial option will cause that the first run of RavenDB 4.0 server will launch the Setup Wizard and guide you through authentication and cluster setup.
