7.12 cluster ![7.12](https://us1.discourse-cdn.com/elastic/original/3X/e/8/e8db1707a6679f92cfe1cb3d1905af41714c32e4.png) ![7.12 2](https://us1.discourse-cdn.com/elastic/original/3X/d/4/d40f9fee8eb4f3ebefb5449f2728d29393a6829c.png) 7.16 ![7.16](https://us1.discourse-cdn.com/elastic/original/3X/c/2/c27b35de8d36847facee6be7cfa51542eb7d6858.png) ![7.16 2](https://us1.discourse-cdn.com/elastic/original/3X/c/8/c8a96390cffe7eaed162b3164718069004792125.png) I made a snapshot on the 7.12 cluster, shared the snapshot using NFS, then created a new 7.16 cluster, mounted the nfs path, and registered the warehouse with the same name on kibana. After the registration, I browsed the snapshot UI and found Didn't find any existing snapshots, is this the wrong way to do it? I see that Elasticsearch cloud service has such an [operation case](https://www.elastic.co/guide/en/cloud/current/ec-migrate-from-aws.html), I don't know if it is also suitable for private deployment environment. Also I have a question, will snapshots keep xpack authorization records? ---

Did you mount the repo on the newer cluster as read-only? > **[Restore a snapshot | Elasticsearch Guide \[7.16\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.16/snapshots-restore-snapshot.html#restore-different-cluster)** ---

On the new cluster, I deleted the previously registered repo and created a new type:url repo. The same operation, the prompt I got is still [local:snapshot\_2] snapshot does not exist ```auto PUT _snapshot/local { "type": "url", "settings": { "url": "file:/home/esdata/snapshot" } } POST /_snapshot/local/snapshot_2/_restore { "error" : { "root_cause" : [ { "type" : "snapshot_restore_exception", "reason" : "[local:snapshot_2] snapshot does not exist" } ], "type" : "snapshot_restore_exception", "reason" : "[local:snapshot_2] snapshot does not exist" }, "status" : 500 } ``` ---

I noticed that [other people's solutions](https://stackoverflow.com/questions/54598720/elastic-search-snapshot-restore-another-cluster/70678529#70678529) are to directly overwrite the data of nodeA to the data of nodeB, but I saw in the elastic documentation that nodeB can only mount the NFS directory in read-only mode. Is my understanding wrong? ---

I installed the cluster of version 7.16.3. I replaced the snapshot directory generated by version 7.12.0 with the directory created in advance by version 7.16.3, and then prompted that "[local:beifen/WMgGeuykR-KMhD96mwcnRw]" was missing. In this case, it should be It is not possible to directly use the method of directory replacement. I want a more professional answer. ---
