HI,

we upgraded recently from 1.x to 2.x. we are using mapper-attachment plugin for the index we are using in 2.x which is having index\_name field.  
While upgrading to 5.x, we are unable to reindex the index.  
This index was created in 1.x  
Can anyone help me how to reindex the index.

Error we are getting:

> PUT http://\<ip:9200/documents-2.4.4 failed with [400] Mapping definition for [fields] has unsupported parameters: [encoded\_attachment.content : {type=string, index\_name=encoded\_attachment}]: {}
