Hello There
1. Describe your incident:
We are receiving below error while upgradding ES from 6.8 to 7.16
The index [graylog_1082/WFeFroGmSUKbClpNJiuJdw] was created with version [5.6.5] but the minimum compatible version is [6.0.0-beta1]. It should be re-indexed in Elasticsearch 6.x before upgrading to 7.16.1.
2. Describe your environment:
-
OS Information:
Debian linux (docker container) -
Package Version:
Graylog 4.2.5
ES : 7.16.1
Mongo : 4.4.12 -
Service logs, configurations, and environment variables:

3. What steps have you already taken to try and solve the problem?
