I'd upgrade to latest 1.7, then install the migration plugin and check what is needed. Then upgrade to 2.4 if possible.

But I'd probably go another route:

Start a 5.2 cluster
Use reindex from remote API to read data from 1.3 cluster.

Hi,

Actually i already backup the nodes data from Elasticsearch 1.3.9 to D:\D\Backup_data

PUT /_snapshot/timo_backup2
{
"type": "fs",
"settings": {
"compress" : true,
"location": "/D/Backup_data/"
}
}

i have try this command at elasticsearch 2.4
POST /_snapshot/timo_backup2/snapshot-number-one/_restore

but have error
{
"error": {
"root_cause": [
{
"type": "repository_missing_exception",
"reason": "[timo_backup2] missing"
}
],
"type": "repository_missing_exception",
"reason": "[timo_backup2] missing"
},
"status": 404
}

Now how to restore my data from D:\D\Backup_data to Elasticsearch 2.4?

Thanks

Best regards
Sharon

You did not upgrade to 1.7 first?
I mean that IIRC you can only use the migration plugin on 1.7.

But that was not your question.

In the repository location I think you are missing the D: part.
