How to transfer certain vectors from one class to another?

I currently have a class with lets say 100 vectors, and I want to make a new class with 80 of them that have a similar property. How can I do this in the most efficient manner?

Hi @Siddhi_Bansal we have a highly voted roadmap feature for reindexing Reindex API (Inverted Index) · Issue #2359 · weaviate/weaviate · GitHub that will be the future solution for this.

As a workaround for now you can transfer data using the cursor api with an example here.
