Porto WP theme to be applied to an existing WP website

I have an existing WordPress/WooCommerce website that needs a new theme to be applied.

The existing website can be found here https://evoleze.com/ (which uses the Jupiter WP Theme)

I have a development website with the new theme already uploaded and activated with demo content here https://dev.smewebdesigns.com/
It uses the Porto Digital Agency2 Dark WP Theme https://www.portotheme.com/wordpress/porto/digital-agency2-dark/

The dev site also has all the content from the live site.

I want the dev site to be updated so that it reflects the live site in terms of pages and content but with the new Porto theme applied. It should make use of the dynamic blocks the new theme offers.
