Hi Folks,

I have troubles starting Elasticsearch.service after the upgrade from 6.8.22 to 7.14.2.

The errors are related to:

- failed to load plugin class [org.Elasticsearch.xpack.security.Security]
- Realm settings have been changed to include the type as part of the setting key
- Found invalid config: xpack.security.authc.realms.ldap1.secure\_bind\_password

Could you give me hints how to solve these, I have tried a lot of things?

Have you looked at the [migration guide](https://www.elastic.co/guide/en/elasticsearch/reference/7.16/breaking-changes.html) or [upgrade guide](https://www.elastic.co/guide/en/elastic-stack/7.16/upgrading-elastic-stack.html)?

The [migrating to 7.0 page](https://www.elastic.co/guide/en/elasticsearch/reference/7.16/breaking-changes-7.0.html) lists all the breaking changes between 6.x and 7.x and advice on how to resolve them.

In general, we recommend using the [Kibana Upgrade Assistant](https://www.elastic.co/guide/en/kibana/6.8/upgrade-assistant.html) in 6.8 to prepare for your upgrade to 7.x so that you can resolve these issues ahead of time. If that's still an option for you, it might be the best path forward.

Hi Tim,  
Yes, I have been using these articles and I configured the Elasticsearch.yml according the documentation.  
Still nothing helps.

The issue you have here:

> [@Penchev](#):
>
> ```auto
> Found invalid config: xpack.security.authc.realms.ldap1.secure_bind_password
> 
> ```

is covered in the breaking changes here:

- [Breaking changes in 7.0 | Elasticsearch Guide [7.16] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.16/breaking-changes-7.0.html#include-realm-type-in-setting)

You need to remove `xpack.security.authc.realms.ldap1.secure_bind_password` from your elasticsearch keystore, and (unless you have already done so) add `xpack.security.authc.realms.ldap.ldap1.secure_bind_password` instead.

Thank you. This worked in my case.
