We have a new website on a new url (been up for around 2 years now) and our old website is slowly fading in the background, we are now at the point where the money is still ok but we are having issues running both side by side, we have a calculator on each page and are thinking about removing this and adding a box with please order from our new site here (with url of similar page).
Now the issue is we don't want to link for SEO purposes and google hammer us (thinking of no - following these) and we also have a penalty we got in 2012 on the site but we did get out of this, would this cause any issue to the new site?
