Migrating wordpress site with the duplicator plugin

I have gone through the user guide on how to use duplicator plugin. I want to migrate the website to a sub folder area on the live site and keep the main page 'under construction'. I see the instructions say that i can copy the archive and the installer file to the public_html folder and create a db and install which will migrate the local site to the main domain area. I want to find out if this can be done in a new path under the main domain so i can test it and move it back to the main page. Let me know.
