I tried to upgrade from 6.5.2 -\> 6.8 -\> 7.5  
The upgrade assistant in 6.8 said indices are good to go for upgrade.  
But after upgrade to 7.5, when I start kibana, i get a Fatal error:

` Error: [mapper_parsing_exception] Root mapping definition has unsupported parameters: [_all : {enabled=false}]`

Indeed all the indices have this in the mapping.

```
{
  "log-batman-2019.01" : {
    "mappings" : {
      "_all" : {
        "enabled" : false
      },
      "properties" : {
        "@timestamp" : {
          "type" : "date"
        },
        "exceptions" : {
        ......
        ......

```

I am wondering what went wrong? Upgrade Assistant should have given me a warning if this was an issue.

And what is the way forward? Should I be reindexing everything? Or should I update the mapping of the existing indices to remove the \_all field (If such thing is possible)?

Elasticsearch is working fine. I am thinking if this has something to do with kibana.  
I did remove the .kibana\_1 and some more of those indices. I just kept the .kibana\_10 which is currently pointing to .kibana. Was this something I should not have done?
