Hi, Is it possible to migrate an elasticsearch index from one graylog to another graylog server? I don’t need to migrate the entire graylog. Just a particular elasticsearch index. ---

Hello @syntax Yes this is posibible. I performed this on one of my CentOS 7 server and migrated to Ubuntu 20.0.4. > **[Snapshot and restore | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/snapshot-restore.html)** It was actually simple just like a MySQL Dump. One issue I did run into was when I started the restore proccess. If this error occurs check index your indice > ERROR [IndexRotationThread] Couldn’t point deflector to a new index > java.lang.IllegalArgumentException: [alias] is unsupported for [REMOVE\_INDEX] `curl -XGET 'http://localhost:9200/_cat/indices?pretty=true'` I belive this was due from my restore index had the same name as my index on the new node. Since this was a new Graylog Server I just deleted the index on the new node and executed the restore process. Hope that helps ---

hi gsmith. thanks for the reply once again. a few questions, 1. how does graylog detect the restored index? 2. does this process work for multi-node setup? ---

Hello, > [@syntax](#): > > 1. how does graylog detect the restored index? Only thing I did with Graylog is restart the service, so yes. Dont have indices with the same name when you do a restore and your good. Have a look here on that subject, @aaronsachs explains this procedure well. > [@Elastic Restore Help Please](https://community.graylog.org/t/elastic-restore-help-please/19161/16): > > @mntbighker I’ve not forgotten about this–it’s just taken longer than I expect because my normal day-to-day duties have kept me pretty busy. I want to ensure I understand what you’re expecting to see. My read is that you’re expecting to see the renamed Graylog indices (both those prefixed w/ graylog- and gl\_) just show show up in Graylog–is accurate? If so, there’s additional steps that have to happen for an index to show up in Graylog, and those additional steps are what I was unaware of earlie… As for > [@syntax](#): > > 1. does this process work for multi-node setup? To be honest, I have not done this on a multi node setup yet. I would image it can be done. If you have a cluster this could be dupicated on each ES node. All I used was `scp` command to migrate my indices to another node and performed a restore. NOTE: Make sure the vsersion of Elasticsearch is the same before you do a restore or you might run into trouble. Hope that helps ---

For the multi-node question, a snapshot/restore works for a single-node or multi-node deployment since this is done through the API. ---
