Hi, Is there any possibility for doing such downgrade without data loss? I have seen [this topic](https://discuss.elastic.co/t/downgrade-from-es-8-10-1-to-8-9-2/343919) and [this one](https://discuss.elastic.co/t/downgrade-elastic-search/289286) before. but I don't have a snapshot before the 8.15.0 version and tried snapshot of 8.15.0 on elastic cluster version 8.13.4 but I get following error: `{"error":{"root_cause":[{"type":"snapshot_restore_exception","reason":"[my_backup:snapshot_1/iqQ0hbqlSlSnDe7SHZaGfQ] the snapshot was created with version [8.13.4-snapshot[8512000]] which is higher than the version of this node [8.13.0-8.13.3]"}],"type":"snapshot_restore_exception","reason":"[my_backup:snapshot_1/iqQ0hbqlSlSnDe7SHZaGfQ] the snapshot was created with version [8.13.4-snapshot[8512000]] which is higher than the version of this node [8.13.0-8.13.3]"},"status":500}` ---

Elasticsearch does not support in-place downgrades, so the only ways to move to a prior version are: 1. Restore snapshot taken in a version earlier or equal to the one restoring to 2. Setting up a new cluster with the lower version and the reindex into this from the remote cluster with the higher version Why do you want to downgrade? ---

Thank you for your response. I want to downgrade because spring boot's current version is not fully compatible with latest version of elasticsearch. I will follow [this reindex guide](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html#reindex-from-remote) and i hope it works. ---

Elasticsearch is designed so that older clients can connect to new servers _(but not necessarily the reverse)_. You should not have any issue using Spring Boot and the 8.13 client against an 8.15 server ---

@TimV It connects to Elasticsearch 8.15 successfully, but after I upgraded to this version, the client encounters timeouts after a while. I hope downgrading the server will solve this problem. example: ```auto org.springframework.dao.DataAccessResourceFailureException: 30,000 milliseconds timeout on connection http-outgoing-2 [ACTIVE] at org.springframework.data.elasticsearch.client.elc.ElasticsearchExceptionTranslator.translateExceptionIfPossible(ElasticsearchExceptionTranslator.java:111) at org.springframework.data.elasticsearch.client.elc.ElasticsearchExceptionTranslator.translateException(ElasticsearchExceptionTranslator.java:65) at org.springframework.data.elasticsearch.client.elc.ElasticsearchTemplate.execute(ElasticsearchTemplate.java:685) at org.springframework.data.elasticsearch.client.elc.ElasticsearchTemplate.doIndex(ElasticsearchTemplate.java:234) at org.springframework.data.elasticsearch.core.AbstractElasticsearchTemplate.save(AbstractElasticsearchTemplate.java:203) ``` ---

It sounds like you would be better off trying to diagnose and fix the timeout issues than trying to downgrade (which may not even solve the problem) ---

As Tim said, check your url connection by curl. Might be: - ES service hasn't been properly started, check ES logs - network.host param in elasticsearch.yml - firewall has been activated - http or https setting has been changed
