How to move data in a ingest node to data node

Hi,
I have a cluster with 4 nodes.
node1-master
node2-master
node3-ingest
noode4-data

Now ingest node fully filled with data and can not start elasticsearch service.
I want to move data from ingest node to the data node.

I want to how to transfer data from ingest node to data node.
I'm using ELK 7.10.1 version.

Thank You!

Data should be balanced between all nodes automatically.
Does that node have different storage space compared to the others?
