How to import components into a Jira project
Use the import functionality to quickly create components in your Jira project. You can import:
all components that are in your Jira instance
components tagged with a certain label
components that aren’t tagged with any label
Import components
Navigate to the Project settings > Import components
In the drop-down, select the group of components for import.
Click Import components.
Components are now imported into the project.
Imported components automatically become part of the cross-project components group. Changes to these components are going to be synchronized across the projects.
