This question is in reference to Atlassian Documentation: Managing components
How can i re use an existing group of components to another project
You cannot. They are purposefully designed as project-specific values. The feature suggestion is here: https://jira.atlassian.com/browse/JRA-8663
I sincerely suggest that you vote on the request and detail your usecase.
Thanks Steve. I voted and watched that issue as well
