Hi everyone, I have a couple of questions about clustering and changing node roles:

For all scenarios below, I would first shut down the entire cluster, make changes to the config files for each node and bring the cluster back up.  
I am looking to implement scenario 1 down the line, scenarios 2 and 3 are stated to understand behaviour.

**Scenario 1**  
Changing a data-only node to master+data

- I would imagine this would work seamlessly? It would continue to hold its own primary shards and replica shards from other nodes, but would also now participate in master responsibilities.

**Scenario 2**  
Changing a master+data node to data-only

- Again, would this work seamlessly?

**Scenario 3**  
Changing a master+data/data-only node to master-only

- Would the primary and replica shards be transferred to other nodes in the cluster or do I have to manually transfer/route them?

Thank you!
