Youtube Strategy (Upload date)

So i have around 60 videos up.
10 different videos uploaded 6 times.
The videos are from 2011-2012
Around 50-60 likes per video
Around 10-20 comments per video

They make me only 100-200$ a month now. They used to make me 1-2k a month.
They hardly get any views now.
All the videos are high ranked for their keyword but within their niche, the newer the video the more views you get.

What i was thinking:
The comments are from 1-2 year ago, i would delete them all and replace them with newer recent ones.
Or keep the old comments and add the new ones with them.

I want to trick the viewer thinking it's a new video, but the upload date ruins it.
Is there any way i can keep the ranking but change the upload date?
Any tips will be greatly appreciated.

Thank you for reading.

Well you could just add some new comments . Do people really check the upload date that much ? I know I don't really check it sooo :-??

well you can just create another video and just rank it again

Being in the youtube game for such a long time, i check everything. Not sure if the average viewer does the same.

The upload date is the main reason my videos rank so high, i am the only one with an upload date from 2011/2012.

I would get a fresh page of comments and just see how that goes, you don't have to necessarily delete the old ones, just get them off the first page. As for if people are still going to check the upload date, I would imagine that depends on the niche and how you're monetizing the video.
