currently, my Graylog is working on VM.
my Gralog version is 3.2.4 and now I want to upgrade it to the latest version without losing any of my data.
so I have tried locally to set up the 3.2.X version and put some dummy data in it. take backup of MongoDB, elasticsearch and graylog individually using mongodump, snapshot, content-pack methods respectively, and after I upgrade graylog to the latest version. but when I’m trying to restore the data some of the data get failed to restore in mongo and also in graylog content-pack. also dashboard configuration was not restored.
can someone guide me on this. how can I upgrade my graylog to the latest version without losing any of the data and current configuration?
