Hi,
Based on the reference documentation it should be possible to restore a snapshot taken on Elastic 6.x on a 7.x cluster: https://www.elastic.co/guide/en/elasticsearch/reference/current/snapshot-restore.html
I've tried this with no success. What I did is this:
- Create a fs repo in the 6.2 cluster
- Take a snapshot
- Copy entire repo folder to 7.7 cluster
- Create fs repo with copied files in 7.7 cluster
When i now try to list the snapshots in the repo, i get an empty list back
curl -X GET "localhost:9200/_cat/snapshots/myrepo?v"
id status start_epoch start_time end_epoch end_time duration indices successful_shards failed_shards total_shards
No warnings or errors in the logs.
When i create a new snapshot on 7.7 its created and then is also listed with the above command, but the 6.2 snapshot remains missing.
Any idea what I might do wrong? Do I misread the documentation and it not supported?
Best,
Toni
