When Removing default path settings elasticsearch fails starting

Elastic Stack Elasticsearch
1

Hello,
I want to upgrade my 5.6.5 ES cluster to v6.2 using the Upgrade Assistant and i get an error that states

   Default path settings are removed
    This issue must be resolved to upgrade. Read Documentation

but i already have path.data and path.logs set in my elasticsearch.yml file :

  path.data: /var/lib/elasticsearch
    path.logs: /var/log/elasticsearch

So i try to remove default path settings in /usr/lib/systemd/system/elasticsearch.service:

-Edefault.path.logs=${LOG_DIR}
-Edefault.path.data=${DATA_DIR} \

but after that when i try to start ES using systemctl it fails whit the following error and no logs written:

    Exception in thread "main" org.elasticsearch.bootstrap.BootstrapException: java.nio.file.NoSuchFileException: /usr/share/elasticsearch/config
