I created the snapshot of my old version 7.x elk stack , and I now I am trying to restore the old snapshot on the new eck-elasticsearch version 8.14.3.

### Context:

- Upgraded from Elasticsearch v7.17.22 to v8.14.3 using ECK (Elastic Cloud on Kubernetes)
- Configured S3 for storing snapshots
- Initiated restore process from a v7.17.22 snapshot to the v8.14.3 ECK-Elasticsearch cluster

### Steps Taken:

1. Successfully restored data indices

- All data indices are visible and accessible in the v8.14.3 ECK-Elasticsearch cluster

1. Attempted to restore system indices:

- `.ds-.slm-history-*`
- `.ds-ilm-history-*`

### Current Situation:

- The system indices (`.ds-.slm-history-*` and `.ds-ilm-history-*`) were successfully restored
- However, the associated data streams (`.slm-history-5` and `ilm-history-5`) are not present in the v8.14.3 cluster

### Expected Behavior:

After restoring the `.ds-.slm-history-*` and `.ds-ilm-history-*` indices, we expected to see the corresponding data streams (`.slm-history-5` and `ilm-history-5`) automatically recreated in the v8.14.3 cluster.

### Question:

Is this behavior expected when restoring from a 7.x snapshot to an 8.x cluster? If so, what are the recommended steps to properly recreate these system data streams while maintaining the historical data contained in the restored indices?
