If ElasticSearch indices have been created with an invalid name, the ElasticSearch migration will fail with the following error:
Bash
2026-Feb-18 12:39:57 PM [main] ERROR com.veridiumid.persistence.migration.Main
co.elastic.clients.elasticsearch._types.ElasticsearchException: [es/indices.create] failed: [invalid_alias_name_exception]
Invalid alias name [ELK_KEYSPACE.ELK_INDEXNAME]: an index or data stream exists with the same name as the alias
java.lang.RuntimeException: co.elastic.clients.elasticsearch._types.ElasticsearchException: [es/indices.create]
failed: [invalid_alias_name_exception] Invalid alias name [ELK_KEYSPACE.ELK_INDEXNAME]: an index or data stream exists
with the same name as the alias
Resolution:
Delete the incorrectly named indices and re-run the migration. This can happen for identity_deprovision and dormant_device
To delete the indices run the following command:
Bash
## take index name:
eops -l | grep dormant_device
eops -l | grep identity_deprovision
eops -x=DELETE -p=/veridium.dormant_device
eops -x=DELETE -p=/veridium.identity_deprovision
##create index with proper templates:
bash /opt/veridiumid/migration/bin/elk_ops.sh --update-settings
## migrate data
/opt/veridiumid/migration/bin/migrate_to_elk.sh -x
/opt/veridiumid/migration/bin/migrate_to_elk.sh -y
To re-run the migration you can use the following commands:
This is the proper fix, delivered in 3.9, but can be applied after the update of 3.8.4:
###elasticsearch/index-templates.json
## modify rollover_alias to be identity_deprovision instead of identity-deprovision
## modify rollover_alias to be dormant_device instead of dormant-device
###elasticsearch/lifecycle-policies.json
##modify the policy for these 2:
{
"policyName": "identity-deprovision-policy",
"content": {
"policy": {
"phases": {
"hot": {
"actions": {
"rollover": {
"max_primary_shard_size": "50gb"
}
}
}
}
}
}
},
{
"policyName": "dormant-device-policy",
"content": {
"policy": {
"phases": {
"hot": {
"actions": {
"rollover": {
"max_primary_shard_size": "50gb"
}
}
}
}
}
}
},
## delete index:
eops -l | grep dormant_device
eops -l | grep identity_deprovision
eops -x=DELETE -p=/veridium.identity_deprovision
eops -x=DELETE -p=/veridium.dormant_device
## create proper indexes format:
/opt/veridiumid/migration/bin/elk_ops.sh --update-settings
##migrate data:
/opt/veridiumid/migration/bin/migrate_to_elk.sh -x
/opt/veridiumid/migration/bin/migrate_to_elk.sh -y
## check - there should be no errors
