从MongoDB v2.4导入索引到MonDB v3.6.4

Question

我已经将collection.bson文件从MongoDB 2.4迁移到MongoDB 3.6.4，作为collection.json。

但是，在collection.metadata.json 2.4中，它们是另外一个文件MongoDB。

如何将其导入MongoDB 3.6.4？

collection.metadata.json的含量如下；

{
  "options": {
    "create": "collection"
  },
  "indexes": [
    {
      "v": 1,
      "name": "_id_",
      "key": {
        "_id": 1
      },
      "ns": "emgda.collection"
    },
    {
      "v": 1,
      "name": "customerId_1_elementId_1_siteId_1_createdTimestamp_1",
      "key": {
        "customerId": 1,
        "elementId": 1,
        "siteId": 1,
        "createdTimestamp": 1
      },
      "ns": "emgda.collection",
      "background": true,
      "sparse": true
    }
  ]
}

蒙戈恢复版本如下，

emgda@ubuntu:~/trial$ mongorestore --version
mongorestore version: r3.6.4
git version: d0181a711f7e7f39e60b5aeb1dc7097bf6ae5856
Go version: go1.7
   os: linux
   arch: amd64
   compiler: gc
OpenSSL version: OpenSSL 1.0.2g  1 Mar 2016

注意:当我使用mongoretore -d emgda auditing.bson时，我得到的集合错误如下。

checking for collection data in auditing.bson
reading metadata for emgda.auditing from auditing.metadata.json
Failed: emgda.auditing: error creating collection emgda.auditing: error running create command: BSON field 'OperationSessionInfo.create' is a duplicate field

我不得不手动从"options": { "create": "collection" },文件中删除*.metadata.json，而rest工作得很好。
