Hello guys,  
18 index has been migrated as well from old cluster with ES 1.7 to a new cluster with ES 2.0, but I have a problem with 1 index, here is the message:

```
 curl -XPOST http://cviadpzl01:9200/_snapshot/my_backup/snapshot_7/_restore?pretty
{
  "error" : {
    "root_cause" : [ {
      "type" : "snapshot_restore_exception",
      "reason" : "[my_backup:snapshot_7] cannot restore index [graylog2_19] because it cannot be upgraded"
    } ],
    "type" : "snapshot_restore_exception",
    "reason" : "[my_backup:snapshot_7] cannot restore index [graylog2_19] because it cannot be upgraded",
    "caused_by" : {
      "type" : "illegal_state_exception",
      "reason" : "unable to upgrade the mappings for the index [graylog2_19], reason: [Mapper for [_timestamp] conflicts with existing mapping in other types:\n[mapper [_timestamp] is used by multiple types. Set update_all_types to true to update [format] across all types.]]",
      "caused_by" : {
        "type" : "illegal_argument_exception",
        "reason" : "Mapper for [_timestamp] conflicts with existing mapping in other types:\n[mapper [_timestamp] is used by multiple types. Set update_all_types to true to update [format] across all types.]"
      }
    }
  },
  "status" : 500
}

```

here an other message in logs:

```
Caused by: java.lang.IllegalArgumentException: Mapper for [_timestamp] conflicts with existing mapping in other types:

        at org.elasticsearch.cluster.metadata.MetaDataIndexUpgradeService.checkMappingsCompatibility(MetaDataIndexUpgradeService.java:329)

```

So the problem is with Mapper for \_timestamp, someone knows how to fix it?.

Thank you.

I am having this exact same issue with the @timestamp field when indexing the data/events sent with logstash. More detail to this problem: [https://www.elastic.co/blog/great-mapping-refactoring](https://www.elastic.co/blog/great-mapping-refactoring)
