How to convert default index template from 5.6 to 7.9?

[jze]

Hello,

I have from ELK 5.6 stack this default index template definition:

   },

            "version":{
               "type":"integer"
            }
         }
      }
   }
}

If I try to set it in 7.9 I get the "Root mapping definition has unsupported parameters" error.
It seems that multiple mappings (config, index-pattern, visualization, ...) are not supported this way anymore.
How do I set the same in 7.9 ?

I would suggest that altering the Kibana template/mapping is not a good thing.

What problem are you trying to resolve by doing this?

[jze]

The ELK server was handed over to me when my colleague left and I need to upgrade it as I need a feature not available in the old version. I admit I don't understand it much so I want to keep it the same way as it was configured.

[warkolm (Mark Walkom)]

Again, I would suggest that is not the best idea.
