What is the best way to clone a WordPress site?

Question

CMS

Hello!
Suppose the customer has a website on WP and he set the task of making a complete copy (design, functionality, structure) of this site on another domain, also on WP.
At the same time, the customer does not give any access to the site (neither to the admin panel, nor to ftp, nor to the database).
The order must be made, there are no options.
Any advice on the best plan to carry out this madness?

Answer 1

Increase the original price tag of the order by 15 times.
To the customer’s question “WTF?”, in a calm voice you explain that this includes the cost of hacking servers, ftp, etc. of the customer.
In general, as you rightly wrote above, you don’t agree on something ...

Answer 2

try to rip him off

Answer 3

Is contacting the old developer not an option? Many leave copyrights and links to their resources... You can find similar templates, modules and plugins. Parsing content is not a problem, with images and text. And then upload to your database
