WP Admin only works on old domain

Hi there.
All works great after i use WP Clone plugin, but when I login in the /wp-admin in the new domain, it takes me to the old domain dashboard….

Please let me know whats wrong and if its posible to fix that, so i can make changes in my new domain.

Thanks in advance!
Diego
