As i would like to upgrade my kibana 5.0 to 5.4, could you please help me in knowing the procedure or process for it.
As uninstall and re-install will be easy but the data (visualizers, dashboards and scripted fields) which were created in 5.0 will be lost when re-install to 5.4 happens.
so overcome this can you please let me know the procedure so that upgradation should happen without any data loss.
simullary procedure for Elastic search and logstash as well for upgradation
the upgrade procedures within major versions of the Elastic stack are quite straightforward. They are described in the respective documentation for each product:
Since Kibana stores its saved objects (visualizations, dashboards, etc...) inside Elasticsearch, it will not lose data as long as the Elasticsearch upgrade is performed in a way that avoids data loss. Please consult the documentation linked above for step-by-step instructions.
