How can I copy the entire _site folder from my Jekyll Blog Site to a Blog folder of my main Website hosted in Linux

I have my website with HTML/CSS/JS/PHP files hosted on a Godaddy Shared VPS with cpanel. Now I have created a Jekyll Blog Site on my local machine (Mac OS X). I want to copy the entire contents of this blog (_site folder?) to the subfolder called 'blog' in my website called '_public_html/blog'.

Is this doable? If not, what is a recommended approach to export my blog site to my main website blog folder?

Thanks in advance.
