Step 3: Customize the migration options

1. From the same shell on the bootstrap instance, find the cdk.context.json file in the current, /opensearch-migrations/deployment/cdk/opensearch-service-migration, directory. The cdk.context.json file contains a default context block that has already been populated with the given stage and network defined in the CloudFormation Parameters. The targetCluster and sourceCluster details should be filled in before moving to the next step.

   Because multiple migration options might change frequently, refer to Configuration Options for configuration options based on your use case.

Note

The Migration tooling expects the source cluster, target cluster, and migration resources to all exist in the same VPC. If this isn’t the case, manual networking setup outside of this documentation is likely required.
