I recently got a YouTube account from someone, but I would like to be able to login with the Google account that I already have and connect it to the former YouTube account.
How can I add my own Google account (Gmail address) as a "manager" of the YouTube account (which is connected to its own Gmail account)? Or, vice versa, how can I add the YouTube channel to my Gmail account?

Short answer
At this time it's not possible to move Youtube product data but it's possible to have several managers for Youtube channels linked to Google+ pages.
