Hi,  
I have upgraded from v6.8 to v7.2 and everything seemed ok but when I tried to start my single instance, I faced these messages:

```
[2019-07-04T18:18:30,188][ERROR][o.e.b.Bootstrap] [saelklab1.crifnet.com] Exception
java.lang.IllegalArgumentException: unknown secure setting [xpack.ssl.truststore.secure_password] did you mean any of [xpack.http.ssl.truststore.secure_password, reindex.ssl.truststore.secure_password, xpack.http.ssl.keystore.secure_password, xpack.security.http.ssl.truststore.secure_password]?

Suppressed: java.lang.IllegalArgumentException: unknown secure setting [xpack.ssl.keystore.secure_password] did you mean any of [xpack.http.ssl.keystore.secure_password, reindex.ssl.keystore.secure_password, xpack.http.ssl.keystore.secure_key_password, xpack.http.ssl.truststore.secure_password, reindex.ssl.keystore.secure_key_password, xpack.http.ssl.keystore.key_password, xpack.security.http.ssl.keystore.secure_password]?

```

I'm not understanding this issue since I have not configured those keys into my elasticsearch.yml  
Furthermore, I'm not finding any files where they are located.
