Hello all, I am running into an issue where I am receiving the following error: can not be imported as a dangling index, as index with same name already exists in cluster metadata I know that I am getting this error because I have an index that is named graylog\_2 and I am attempting to "merge" and old graylog\_2 index. My question, is how do I do this correctly? The old graylog\_2 index has old data from months ago that I am looking to get reimplemented to our graylog cluster and the new graylog\_2 index has information from a few days ago, that is also necessary to have. Thanks. ---

The simplest way would be to open the old index in another cluster and reindex it into the new index using reindex API. ---

Hey Igor, Thanks for the reply on this. So would this mean, that I could take the folder structure from one server to another server, rename it and then move the newly reindexed node back to the original server? I attempted to test this and received an error along the lines of Limit of total fields [1000] in index [] has been exceeded and I am not sure why. If I am reindexing, it shouldn't be creating new fields right? ---

What I am attempting to do, is take the folder structure of my index, move it temporarily to another elasticsearch cluster (A sandbox that was built) and reindex it. Is there a better way of doing this or is this the incorrect way of doing this? Unfortunately, my inexperience with elasticsearch seems to make this process more daunting than I expected. ---
