remote es version : 7.6.0  
reindex es version: 6.5.3

Aren't you supporting reindex of version es6 from version es7?

Thank you for your reply in advance.

You want to downgrade? Is that right?  
Why do you want to do such a thing?

First of all, thank you for your answer.

Yes, I'm going to downgrade.  
This is because I want to move the index of es7 that I created for testing to es6 that is currently linked to something else.  
I can index es6 from the original data, but I thought it would be convenient to use reindex api.

Anyway, reindexing from es7 to es6 is not supported, is it?

I guess it's not supported.
