Copy these together with [`migrate-mongo-config.js`](https://github.com/SciCatProject/scicat-backend-next/blob/master/migrate-mongo-config.js) file to a location were you can access your MongoDB instance and have `migrate-mongo` package installed either globally(which is preferred) or locally if global installation is not possible. Then modify the config file to contain your MongoDB instance details like database name and url. Once modified, start the migration by running
