Migration of the Postgres DB from strapi v3.1.4 to strapi v4.2.0

System Information
  • Strapi Version: 4.2.0
  • Operating System: Windows 11
  • Database: Postgres
  • Node Version: 16.13.0
  • NPM Version: 8.1.0

So I need help to migrate my database from the old version to the new one of strapi. The strapi v4 works perfectly with a new fresh empty database, I did update all the controllers, routes, and configs.
But I still need to update the DB. I found this official script GitHub - strapi/migration-scripts: Collection of Strapi Migration scripts that can do it but it’s just not working for me, there are too many things that don’t match, and II guess it is because my strapi v3 is too old, and the script is made for the newer versions of the strapi v3.
Can someone help me and get me some suggestions on what I should do and maybe even guide me down until I get somewhere, would appreciate someone for help!!!
Thanks in advance, and waiting for a reply from some :slightly_smiling_face:
