ES Version Upgrade Check
Last updated: 2025-02-07 11:19:06
Different versions of Elasticsearch have certain incompatible configuration items, and if you have set such items, an upgrade may affect the use of your cluster. You can use the upgrade check feature to check whether there are any incompatible configuration items and adjust them accordingly. The following describes the check to be performed when upgrading the Elasticsearch version.
Warning:
On the details page in the console, click Upgrade in the top-right corner. For detailed directions, please see Upgrading ES Clusters.

Configuration Check for Elasticsearch Upgrade from 5.x to 6.x

How to adjust incompatible configuration items

Cluster level

Snapshot settings You can cancel these settings (including persistent and transient) through the ES cluster settings update API (PUT _cluster/settings):
PUT _cluster/settings
{
"persistent": {
"cluster.routing.allocation.snapshot.relocation_enabled": null
},
"transient": {
"cluster.routing.allocation.snapshot.relocation_enabled": null
}
}
Store throttling settings You can cancel these settings (including persistent and transient) through the ES cluster settings update API (PUT _cluster/settings):
PUT _cluster/settings
{
"persistent": {
"indices.store.throttle.type": null,
"indices.store.throttle.max_bytes_per_sec": null
},
"transient": {
"indices.store.throttle.type": null,
"indices.store.throttle.max_bytes_per_sec": null
}
}

Index level

Similarity settings These settings will be ignored after upgrade to 6.x, which will not affect the upgrade though. To cancel them, follow the steps below:
The index needs to be closed before you modify these settings, and the closed index cannot be read or written. Close the index:
POST my_index/_close
Cancel these settings through the ES index settings update API:
PUT my_index/_settings
{
"index.similarity.base.*": null
}
Then, open the index by running the following command:
POST my_index/_open
Shadow replicas settings
The index needs to be closed before you modify these settings, and the closed index cannot be read or written. Close the index:
POST my_index/_close
Cancel these settings through the ES index settings update API:
PUT my_index/_settings
{
"index.shared_filesystem": null,
"index.shadow_replicas": null
}
Then, open the index by running the following command:
POST my_index/_open
Index store settings
The index needs to be closed before you modify these settings, and the closed index cannot be read or written. Close the index:
POST my_index/_close
Cancel these settings through the ES index settings update API:
PUT my_index/_settings
{
"index.store.type": null
}
Then, open the index by running the following command:
POST my_index/_open
Index store throttling settings Cancel these settings through the ES index settings update API:
PUT my_index/_settings
{
"settings": {
"index.store.throttle.type": null,
"index.store.throttle.max_bytes_per_sec": null
}
}
The include_in_all index mapping parameter A previously created index containing this parameter is compatible after the upgrade and does not need to be repaired.

Index template level

1. Use the GET _template/my_template API to get the incompatible template my_template. There are three incompatible items: index store settings, index template mapping parameter (include_in_all), and index template mapping metafield (_all).
{
"my_template": {
"order": 0,
"template": "my_*",
"settings": {
"index": {
"store": {
"throttle": {
"max_bytes_per_sec": "10m"
}
}
}
},
"mappings": {
"my_type": {
"_all": {
"enabled": true
},
"properties": {
"my_field": {
"type": "text",
"include_in_all": true
}
}
}
},
"aliases": {}
}
}
2. After copying and removing incompatible configuration items from the template, use the PUT _template/my_template API to update the template.
PUT _template/my_template
{
"order": 0,
"template": "my_*",
"settings": {
},
"mappings": {
"my_type": {
"properties": {
"my_field": {
"type": "text"
}
}
}
},
"aliases": {}
}
