1:1 Migration of Dating Service from DatingScript to WP Dating WordPress Script

I am looking for an experienced specialist to migrate the dating section of our portal from the DatingScript v1.2.1 © VLD Interactive Inc system (https://www.datingscript.com). Our current portal is largely based on PHP and includes several modules, with the main one written in Symfony. The migration concerns moving the existing dating data to the purchased WP Dating script on WordPress (https://www.wpdating.com/). Our database, sized at 13GB, contains various segments of the portal such as forums, news, advertisements, but we are focusing solely on migrating dating data such as:

Logins, Email addresses, Profile pictures, Private messages, Timeline comments, Friends Profile fields, namely: Gender, Age, Province, City, Body type, Height, Eye color, Hair, Smoking, Alcohol, Living situation, Music preferences, Marital status, Children, Mobility, Education, Employment status, Industry of work, Interests, A bit about me (text import)

We aim to migrate the dating data on a 1:1 basis. It is crucial for the contractor to have experience working with large and complex databases and to be knowledgeable in PHP and Symfony technologies, which are key to ensuring a smooth migration without data loss. We expect the new system to be stable, tailored to user needs, with intuitive operation, enabling a smooth transition to the new platform.
