How to get there:

You'll be on the Campaigns window of the Control Panel.
Choose the campaign's name or the edit link to the right of it.

What to do:

Click on the Supporter tab. 

Scroll down to the name of the supporter you’d like to make changes to, or enter their last name in the search box. 

Click on the second action item, the transfer button (arrows icon) adjacent to the name.
