Using Admin Toolbox it is possible to perform bulk change actions for all your versions across all Jira projects! These changes include
Updating the name and description of a version
Bulk adding a version to multiple projects
Bulk removing a version from multiple projects
Bulk deleting a version from multiple projects
Grouped by name
All versions in the popup are grouped by name. Even though versions 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 version.
Updating the name of a version will update the version name in all projects where a version with this name is available.
