I am receiving this issue below in ES6.8 when performing the same rollover function I have in ES5.6  
{  
"error": {  
"root\_cause": [  
{  
"type": "remote\_transport\_exception",  
"reason": "[TrekrMZ][x.x.x.x:9300][indices:admin/rollover]"  
}  
],  
"type": "illegal\_argument\_exception",  
"reason": "unknown setting [analysis.analyzer.audmonnormalizer.char\_filter] please check that any required plugins are installed, or check the breaking changes documentation for removed settings",  
"suppressed": [  
{  
"type": "illegal\_argument\_exception",  
"reason": "unknown setting [analysis.analyzer.audmonnormalizer.filter] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"  
},  
{  
"type": "illegal\_argument\_exception",  
"reason": "unknown setting [analysis.analyzer.audmonnormalizer.type] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"  
},  
{  
"type": "illegal\_argument\_exception",  
"reason": "unknown setting [number\_of\_replicas] did you mean [index.number\_of\_replicas]?"  
},  
{  
"type": "illegal\_argument\_exception",  
"reason": "unknown setting [number\_of\_shards] did you mean [index.number\_of\_shards]?"  
}  
]  
},  
"status": 400  
}

I have this as part of the index definition:  
"settings": {  
"number\_of\_shards": 1,  
"number\_of\_replicas": 1,  
"analysis": {  
"analyzer": {  
"audmonnormalizer": {  
"type": "custom",  
"char\_filter": ,  
"filter": [  
"lowercase",  
"asciifolding"  
]  
}  
}  
}  
}
