Cross cluster search question

Hello, I have 3 clusters in my infrastructure and I wanted to know if it was possible to transfer data from the index of these clusters using cross cluster search. Or is there another way to transfer data. I am using the standard license and I wanted to find a way to transfer data using that license.

CCS is search only, it doesn't transfer indexed data.

Cross Cluster Replication can do this for you, but it is not part of the Basic license.
