Updating SEAL Elastic Stack¶

Overview¶

The update consists of a server and a client part which you have to update separately.

Server:

The server part includes Elasticsearch and Kibana. You have to update it on the management server.
Client:

The client part contains Filebeat. You have to update it on the
- PLOSSYS 5 server
- PLOSSYS 4 server

Elasticsearch is set up as a separate service like Kibana and Filebeat.

Therefore the directory structure of Elasticsearch changes.
The content of the current database is transferred automatically during the update.
The name of the corresponding service changes from elasticsearch to seal-elasticsearch.

We strongly recommend you to

back up the Elasticsearch database as described in Source System: Creating Complete Snapshots/Backups and
make screenshots of the dashboards and indices in the discover view.

This allows a quick overview whether the update succeeded.

Use your screenshots to check, whether the database content has been transferred successfully.
- If so, delete the old database directory. You have to delete it manually, as it not deleted by uninstalling the old elasticsearch service:
```
rmdir  C:\ProgramData\Elastic\Elasticsearch\data\nodes
```
- If not, you have to
  - delete the corrupted indices manually and
  - restore the data from the backup made before updating
    
    For details on the restoration, see Target system: Complete Recovery from a Full Backup.
Then check again, whether the database is ok.
Several configuration files are transferred automatically and saved in the new directory structure and named *.imported.

Check the configuration parameters mentioned in this documentation for correctness. The old and new configuration files differ especially under Windows.

For details on the configuration, see Configuring Elasticsearch.
