Is Starting a New YouTube Channel Better Than Reviving an Old One?

So my largest channel feels dead, I am getting barely any views compared to my small business channel and I feel that just fully restarting again may be the best option for me. Has anyone done this before? It feels crazy and risky just starting again. I will let my subscribers know of course but unsure what else I should do to try and retain what I can from the channel. It is about 7 or 8 years old now. I worry that I start the new one and abandon the original and end up with neither channel performing at all. Same time I dont have much to lose at this point with videos performing so poorly. What do you reckon? Anything I should be careful about or should I just risk it yolo haha
