Copied WordPress to root, may I delete subdomain?

How old is your site? Is there a possibility of losing incoming links to your old subdomain or losing search engine rankings?

No one was directed to the subdomain beforehand, it was just a development subdomain before going live.

Still it’s not clear how you moved the site. Possibly following the instructions here: https://codex.www.ads-software.com/Moving_WordPress

OR, have you followed the steps here?

For trouble-free functioning of your site, read the above two codex resources and complete the steps (if any) of the method followed by you.

Hi Krishna,

Thanks for taking the time to reply.

I installed WordPress on a subdomain, not a subdirectory, and finished working on it.

I followed steps on a page (can’t remember exactly which) that said to copy everything in the subdomain where my site was over to my root and upload the same index.php file.

Everything works perfectly, except I’m wondering if I should delete the first copy of the site on the subdomain without causing any problem to the database and breaking the new version of the site now in the root.

However, backup your site so that you can always restore if anything goes wrong.
