[UPDATE] Here is a video that walks you through how to migrate your database from Sqlite to PostgresQL https://youtu.be/ROvjBdI8-MM?feature=shared
You can also use DTS to make this update locally.
- use
strapi exportto export and back up your data. - configure postgreql based on the docs in your local environment
- use
strapi importto import your backup to your postgresql db instance.
I am in the process creating a guide that explains this in more detail.
