Is it safe to rename node in ES 6.8?

Hello

I've googled on the topic but everything I've found is dated 2015; many things could change since that time.

So I'm reasking, is it safe to rename node in 6.8? If the node was already in use, should I do something to prevent possible data loss or lengthy resyncing?

Are you referring to node.name? If so yes, you can do that.

If the node was in use and you don't want the data it held, then you might want to remove anything that exists under the path.data location.
