Here's how I replace a youTube video on my channel. It's basically a redirect. I wish there was a feature to easily overwrite an outdated video, but until YouTube adds it, this is my workaround/solution to redirect traffic from an old video to a new improved video on the same topic.

It's also handy if you (like me) get over anxious to upload a new video and you overlooked a mistake that you just can't live with. That's a problem if the link has already gone out in a newsletter or youTube subscriber email. If you delete the video, anyone who clicks that link will only see "This video has been deleted." with no way to direct them to new video!

So, don't delete it for awhile! Instead, follow my instructions on how to redirect the visitor to your new video, and even be able to explain in the old title and description. Watch my video to see how I do it.

If you try it or have a better solution, let me know in the comments!
Thanks,
Mimi
