Clustering two nodes with different data


I am trying to form a cluster of two elasticsearch nodes. The both nodes have been in production environment for a while, and they both have different data. Is it possible to make a cluster of both nodes? In case it is possible, will the data merge between both two nodes correctly? Or should I expect a problem?

Thank you.

No, that will not work. Reindex data from one node to the other and then let the node join as an empty node.

Thank you!
