hi @user1503 !!

Welcome to our community :hugs:

Sure, you can export your collection configuration into a python dictionary and move it around using json then create a new collection use that configuration.

here is how using Python Client: 4.16.10 and Server: 1.32.9:

client.collections.delete(["Test", "Test2"])
collection = client.collections.create(
    name="Test",
    vector_config=[
        wvc.config.Configure.Vectors.text2vec_openai(name="vector1"),
        wvc.config.Configure.Vectors.text2vec_cohere(name="vector2"),
    ],
    properties=[
        wvc.config.Property(
            name="data",
            data_type=wvc.config.DataType.TEXT,
        ),
        wvc.config.Property(
            name="hotel_id",
            data_type=wvc.config.DataType.INT,
        )
    ]
)
my_collection_schema = collection.config.get().to_dict()
# now let's create a new collection
new_collection_schema = my_collection_schema
# change the collection name
new_collection_schema["class"] = "Test2"
new_collection = client.collections.create_from_dict(new_collection_schema)
# assert their vector configs are the same
assert new_collection.config.get().vector_config, collection.config.get().vector_config

Let me know if this helps!

Happy coding!
