Update 2.4 to 2.9

Dear all, I hope to count on your valuable knowledge.
I’m always very scared about updating opensearch. My current cluster is 2.4.0 and I want to upgrade to 2.9.
To test, I created a new environment and installed 2.4 and migrated to 2.9. After uploading the cluster, only the admin password and the test index with its data were lost, but all dashboards and Visualizes were lost.
I consulted the .kibana index data and the data from these dash and visuals is there, but does not appear when entering the menu.
Any suggestion?

Hey @angelogabeira

Can you show how this upgrade was executed?, perhaps the steps you used?

I simply turned off the docker containers and changed the opensearch version in docker-compose.yml. I just changed 2.7.0 to 2.9.0 and turned the containers on again. I didn’t do anything else.

Hey @angelogabeira

My appologies I didnt know you were using Docker. unfortunately I wont be any help.

@angelogabeira Could you share your docker-compose.yml file? What were the commands to stop the containers and start them again?
