Using Admin Toolbox it is possible to perform bulk change actions for all your components across all Jira projects! These changes include
Updating the name and description of a component
Bulk adding a component to multiple projects
Bulk removing a component from multiple projects
Grouped by name
All components in the popup are grouped by name. Even though components are created on a per project basis and have unique IDs, if they have the same name, they will displayed in the dialog as one component.
E.g. updating the name of a component will update the version name in all projects where a component with this name is available.
