Elasticsearch Version Upgrade

Elastic Stack Elasticsearch
1

Hi ,

We have Elasticsearch Servers running with Es Version 1.4.2,our client
version is 1.4.1.

We are about to upgrade our Es cluster Version to 1.5.1 , my question is :

Do we need to upgrade the client version to 1.5.1 or our current version
should be compatible with the new Version?

Thanks,
Costya.

Just checking ,

so you are sure that there is forward compatibility... and my system will
work fine with Es Client version of 1.4.1 when the server's version will be
1.5.1 , right ?

This should work in both ways.

The client knows what is the node version.
The node knows what is the client version.

So basically, if one knows he should not send a new data because the other one is too old, it will simply ignore it.
Same for reading. If your node is newer, he knows that the client won’t provide X or Y value. So he won’t try to read it.

That said, the best thing to do is to test it! :smiley:

David, is this the case with older versions (both client and server on
0.90.x versions using java client), and across the 0.90 to 1.x boundary, or
only post 1.x?
