Hello everyone,

I was before using Spotify (E-commerce CMS) but abandonned the project for other stuff .
I now delete all my server files to start fresh (without doing anything else than deleting from FTP) and make a new website by using Wordpress (+Woocommerce) with the same domain name...

Because the website was almost nothing there were only 150 pages indexed.
At this time, i did add my domain in the google search console and also add a sitemap

Maybe there are stuff to do for Search engine and i didnt do anything except deleting my old sitemap and select "Ask the search engine to don't index this website" on my new Wordpress website. I still have the domain registred in the search console (Do i have to delete it?) with and without www but i do not have sitemap of the new website (Because not finish yet but already online xD)

Could you guys please tell me what to do to make a clean transition and force google and other search engine to delete the olds links from their database ?

Thank you very much
