Moving data between identical schemas in Sanity.io

I have made a schema and put data into it already. However, I want the data in this schema to be moved to another document (from projects to uniprojects)
How can I do this without manually copying over the data?

The schemas are identical. They have the same fields and everything I just need to segregate my data.

I think you can use this https://www.sanity.io/schemas/migration-script-for-document-types-b3e1d0b5
