I have a Zammad 4.0 running on CentOS 7 (from rpm). The environment is quite old, so it was running with Elasticsearch 5.6 (that seems not supported now). I’ve upgraded to EL 6.8 and all seems ok.
Now I want to upgrade to 7.12 but I have many problems.
Performing a direct upgrade will broke EL, because 7.12 reports that indices are in format 5.6 and are not supported, and a reindex must by performed on 6.8 before the upgrade.
So I tried to perform this upgrade installing Kibana and leaving update assistant to help me. It reports this problem:
This index has more than one mapping type, which is not supported in 7.0. This index must be reindexed into one or more single-type indices. Mapping types in use: [StatsStore, Organization, KnowledgeBase::Answer::Translation, KnowledgeBase::Category::Translation, Chat::Session, KnowledgeBase::Translation, Ticket, Cti::Log, User]
I haven’t any idea about fixing this Someone can help me?
