Hey There Have The Following Issue After Upgrading Server And Trains To 0.16:


I am not sure about the reasons. What you can do is to backup your /opt/trains/data folder periodically (preferably stopping the docker compose before it). Another possibility is to configure your elasticsearch to run as a cluster with 2 or more nodes on the same or different machine. This will allow elastic to replicate your indices to other nodes.
