By using the Import/Export function, you can utilize SLAs that exist in another service project. This prevents you from losing important data while transitioning from one instance to another.
With the Export function, you can:
Take a backup of your SLA configuration
Copy your configurations from this instance to another Jira instance
Transfer changes from a test environment to your production environment
With the Import function, you can:
Restore from backup
Import configurations from another instance
Apply changes from your test environment
Import SLAs and calendars from Jira Service Management
