If you are writing into two indices, like `index_1` and `index_2`, any document added to `index_1` will also be added to `index_2`, so you will have new writes in the `index_1` that will not be present in the current snapshot.

Same thing with updates, unless you update just one of the indices, but again, this will make your data inconsistent between the indices.

As already explained in your other [post](https://discuss.elastic.co/t/transferring-a-writable-index-from-one-cluster-to-another/337934/14), I don't think you can achieve what you want without any downtime
