Hi,
i'm following the migration procedure to upgrade elasticstack from 5.4 to 6.6.1.
But at this point
[https://www.elastic.co/guide/en/elastic-stack/6.6/upgrading-elastic-stack.html#upgrade-internal-indices](https://www.elastic.co/guide/en/elastic-stack/6.6/upgrading-elastic-stack.html#upgrade-internal-indices)
i got two strange behaviors:
1)
pentaho@02srv0094j:~/elk/elasticsearch-6.6.1/config\> curl [http://localhost:9200/\_xpack/migration/assistance?pretty](http://localhost:9200/_xpack/migration/assistance?pretty)
{
"indices" : { }
}
pentaho@02srv0094j:~/elk/elasticsearch-6.6.1/config\>
seems no indices have to be upgraded (but i know that my /data are in 5.4)
1.
~/elk/elasticsearch-6.6.1/config\> curl -XPOST [http://localhost:9200/\_xpack/migration/upgrade/.kibana?pretty](http://localhost:9200/_xpack/migration/upgrade/.kibana?pretty)
{
"error" : {
"root\_cause" : [
{
"type" : "illegal\_state\_exception",
"reason" : "Index [.kibana] cannot be upgraded"
}
],
"type" : "illegal\_state\_exception",
"reason" : "Index [.kibana] cannot be upgraded"
},
"status" : 500
}
Any suggestions?
