How to enable multi tenancy on the existing collection?

hi @arturs_sprogis !!

Welcome to our community

Not all collection configurations are mutable. Here you have a list of what configs are:

Note that you can only change those:

collection.config.update(
    multi_tenancy_config=wvc.config.Reconfigure.multi_tenancy(
        auto_tenant_activation=True,
        auto_tenant_creation=True
    )
)

Because of that you need to enable multi tenancy while creating a new collection, create a new tenant on that new collection, and migrate your data over to it.

Let me know if this helps!

Thanks!
