I have a single elasticsearch node in it's own cluster (one node cluster) and I have different cluster that has 3 nodes. Both have their own set of data. I want to take the single node and add it to the 3 node cluster to make it a 4 node cluster. My question is, will I loose the data that is in the single node when I add it to the 3 node cluster? ---

This is not something that we'd recommend or even say will work. What version are you running? ---

Currently running 7.7.1. I need the data from the single node as well as the data from the 3 node cluster in tact. Is there an alternative? ---

Snapshot and restore or remote reindex. ---

Thanks for providing those options. Not familiar with remote index. I'll look that up. As far as snapshot and restore, the snapshot i would create from the single node wouldn't overwrite any data I have in the 3 node cluster? ---

No it won't. ---
