Until this week moving the linkage from one Google+ product to another was possible only with the help of support. And now we have this über cool tool which allows us to do this ourselves:
You will find a link to it in YouTube settings / Advanced of the YouTube channel you wish to move to a different Google+ product placed as seen above.
Once you click on the link you are shown a super visual interpretation of your current set-up and a box to click to begin the process:
The easy to understand interface gets even better with the next screen where you will see your choices:
There are a couple of caveats here:
1. You cannot link to a Google+ Profile if you have deleted the Google+ Profile as seen here:
It just wont appear as an option because it doesn't exist. And if that is what you wish to link the YouTube channel to then you would need to stop the process and go to Google+ in your Google account and create a new Google+ Profile before returning to your YouTube channel and starting the move process over.
2. You cannot (currently) move the new style custom YouTube /c/ URL with the YouTube channel although you are not told this as seen here:
Final consideration when choosing the Google+ product to relink your YouTube channel to- every Google+ product may only have one YouTube channel on it at any one time. This means that if you pick a Google+ product on that bottom list which has its own channel already you will first be asked to delete it (or cancel the action of course) as seen here:
Be very careful not to delete a YouTube channel you might be super-attached to! Recovering a user-deleted YouTube channel is not easy at best of times but once you move your other YouTube channel to the deleted channel's Google+ product- all the more confusing for everyone!
Instead- consider moving the "blocking" YouTube channel to a different Google+ product before moving your YouTube channel to its Google+ product. ;) That way you keep both!
Here is a video I made about the process (I don't address the /c/ URL caveat in it as I didn't want to confuse folk but might update the video as the tool's development progresses):
Any questions please drop me a note or, better still, pop over to the fora for serious trouble-shooting.
