Unsupported parameters: index_analyzer, auto_boost


I am moving from a self hosted Elasticsearch DB (1.5.2) to Elastic cloud.
The mapping that was used seems not to work anymore:

"Mapping definition for [_all] has unsupported parameters: [index_analyzer : swedish_analyzer] [auto_boost : True]"

Can anyone tell me if it is replaced by something else or or if it is safe to remove it?
When I remove both fields it seems to accept the mapping.

Best regards,

From 2.x, use analyzer instead.
