Backfill Result Validation - opensearch-project/opensearch-migrations GitHub Wiki

After the backfill has been completed and the fleet has been stopped

Refresh the target cluster

Before examining the contents of the target cluster, it is recommended to run a _refresh and _flush on the target cluster. This will help ensure that the report and metrics of the cluster will be accurate portrayed.

Validate documents on target cluster

You can check the contents of the Target Cluster after the migration using the Console CLI:

console clusters cat-indices --refresh

Example cat-indices command output

This will display the number of documents on each of the indices on the Target Cluster. It is further recommended to run some queries against the Target Cluster that mimic your production workflow and closely examine the results returned.
