I ran the migration checker on my Cluster running version 1.7.1 and I get a RED color output error:

Index: .kibana  
Conflicting field mappings  
Mapping for field dashboard:hits conflicts with: search:hits. Check parameter: type

I am running Kibana 4.1.2, how do I fix this so I can move forward with the upgrade.  
Here is few lines from .kibana index  
curl localhost:9200/.kibana?pretty

"dashboard" : {  
"properties" : {  
"description" : {  
"type" : "string"  
},  
"hits" : {  
"type" : "long"

"search" : {  
"properties" : {  
"columns" : {  
"type" : "string"  
},  
"description" : {  
"type" : "string"  
},  
"hits" : {  
"type" : "integer"

Please advice  
Thanks
