Hi all, I have a graylog server with 1.5 billion records. How can I upgrade elasticsearch from version 5 to version 6 without losing all the data that I have now? The instructions on the site are not clear to me. I dont have a cluster, i just havet 1 server with elastic and graylog.

HI @Uporaba,
FIrst, Please ensure that you have backup of your all data before performing this activity. Because without data rollback is not possible in case of any issue while upgrading.
For backup please use snapshot and restore module.
For upgrade, You can follow the same as mentioned in below documents and you can skip the steps which is related to cluster setting as you have only 1 node.

Please do let me know in case of you have further query.
Regards,
Harsh Bajaj

You need to backup of your elasticsearch data i.e. indices.

Hi @Uporaba,
In your error it is showing "type":"access\_denied\_exception".
Yes, please change the directory access as you shown and do let me know if you still facing any issue.
