Describe the issue:
I’m trying to upgrade to version 3.0. But getting this error:
org.opensearch.bootstrap.StartupException: java.lang.IllegalStateException: The index [[.apm-agent-configuration/4B6dvFusQZWVO66YoKQ2Vw]] was created with version [7.10.0] but the minimum compatible version is [2.0.0]. It should be re-indexed in OpenSearch 2.x before upgrading to 3.0.0.
When I try to list indices, I don’t see any such index. Even if I try to delete it ( DELETE .apm*), I’m getting same error
@joelp I’m just curious, did you follow the curl commands shared by @jasonrojas ?
It is important to use superadmin certificate, as most of the hidden indices (.<index_name>) are accessible by a superadmin defined in the admin_dn of opensearch.yml
