New campaign same niche...What to do with my current campaign?

I have a Google display network campaign currently running to a one page squeeze page.
I want to run a new campaign (similar keywords) to a new website (blog optimized as a landing page for Google Ads).
What should I do with my old campaign? Just leave it running? Pause it?

Will my old campaign affect my new campaign in terms of cpc? etc.

 

Generally what people do is run several ad campaigns and see which one works best for their website and overall business.

You can for sure do this.

 

Thanks. I'll keep them both running and try to optimize them both.
