How to Remove Content from Google and Add it to a New Site?

[Crusadex]

Hello everyone, friends. I used to have a personal website before and I have now opened a new website. If I delete the indexed contents of my old site on Google through Search Console and add the content to my new site, will it still be perceived as a duplicate? Additionally, I have removed all the indexes of my old site from Google, and before removal, the articles were appearing as duplicate content in plagiarism checkers. After removing the indexes from Google, I checked and noticed that the articles started to appear as original in plagiarism checkers. If I add the article to my new site now, will it still be considered a duplicate? I have not taken the articles from other sites.
