Hello Ramon and James,
Sorry for the confusion.
https://servicechampions.com/air-conditioning/air-conditioning-installation-and-replacement/ --> current site (accessible directly homepage though main navigation)
will also be available on the new site, with the same URL.
The reason why i post this question is, on the new site, i will be reducing the content on this page (and others) by 80%. That 80% worth of content from the current pages in question, will not exists in the new site. It will not be on the new site because all the content on some pages have been considered to be too exhausting for clients to read and convert to a lead. We have created the new website, same urls, with leaner content to drive more conversions. Less overwhelming to site visitors.
For example, on this page: https://servicechampions.com/air-conditioning/
there are two segments under subheadings: What is an air conditioning system? and another called: How an air conditioner works.
Both of these segments will not be in the new website.
Well, i want to republish the lost content as new blogs. My question was, since the soon to be lost content is currently indexed in google, if i republish them as a new set of blogs after the new site goes live, so will Google see the new blogs as duplicate content since it already has been indexed by them?
