Deploying wordpress without disrupting current html site
Hi, I'm going to upgrade my site from HTML to WordPress. I need some time to migrate the content to WordPress and I would like to install it on the server without the HTML site while I do the work. I'm aware that index.php have priority over index.html. how can I temporarily change the priority? Also, I have a hosting with multiple domains each in a subfolder; may I change the priority only in the subfolder that I need to? Thank you in advance!
