How does project configuration differ in next-gen projects?

Classic and next-gen projects are set up differently. Classic projects share configurations; next-gen projects are configured independently.

In classic projects, fields are placed on screens. Then, screens, issue types, workflows, and statuses are mapped to schemes that are shared across all projects in your Jira instance.

In next-gen projects, admins don’t have to configure schemes and screens. Each project has its own fields, request types, workflows, and statuses: all of which can be configured for that particular project. This means that each project configuration must be configured individually — they can’t currently be shared across projects.
