When publishing a project it will always first transfer to the Staging Runtime. The WEM Staging Runtime is typically used for review and acceptance testing with a (limited) group of testers/users, as a step between Application Development in the Modeler and Usage in Live/Production. ### Hostnames The default URL for the staging environment is https\://\[projectname].staging.wem.io. and can be changed in the portal settings. \ More about changing hostnames can be found here: [Portal Settings](/platform/wemmodeler/project-settings/portal-settings.md#manage-hostnames). ### Database Every environment (Preview, Staging, Live) has its own database. When publishing a project to a new environment you publish the data structure only, NOT its data content. This is necessary to keep the right data in your live environment. When your storage strategy is set to `All portals share the same database` you still have a different database for Staging and for Live used by both portals. More about this here: [Project Configuration](/platform/wemmodeler/project-settings/project-configuration.md#storage-strategy). ### License Before you publish your project to the staging environment you need a valid license. This is a license from WEM giving you permission to publish. You can find out more about licenses [here](https://wem.io/wem-licensing-program/). --- # Agent Instructions This documentation is published with GitBook.
