Promotion of Object from Dev to QA

Hi,

A quick question,

I developed a universe and webi report.

While creating UNX universe in IDT I created secure connection .cns

Now I want to promote all my objects from dev to qa for testing.

Do I need to promote connection as well or does it get promoted automatically when I promote universe (unx file)

I see lot of connections there when I go to Promotion management .

Will appreciate your help,

Thanks

Ron
