I'm reindexing from 6.4 to 7.9 and while I got all documents as it is one thing I noticed timestamp is different, how do I preserve old timestamp in the document?

Hi dadoonet,
Thanks for the quick replay, here is how I'm reindexing it:
```
curl -X POST "https://els02:9200/_reindex?pretty" -u admin:admin --insecure -H 'Content-Type: application/json' -d'
{
"source": {
"remote": {
"host": "http://elk01:9200"
},
"index": "logstash-2020.10.07"
},
"dest": {
"index": "logstash-2020.10.07"
}
}
'
```

Do you have an example of a document from the source which has a different content in the destination? Could you share both?

dadoonet I'm sorry for the trouble I misread it, this is embarrassing 🤦♂️
