Description:
CDF creates a Neptune database using a specific engine version. Upgrading the Neptune engine version is a one-way process. In case of failures, roll back requires restoring from a backup as a new cluster. Also If attempting to upgrade the Neptune engine version using a aws recommended Blue/Green solution, the newly created green Neptune cluster (which will soon be promoted as a production cluster after testing) cannot be imported into the existing CloudFormation stack (cfn-neptune.yaml).

Could someone please share insights on this situation or experiences with performing a Neptune upgrade?

Current behavior:
Upgrading neptune cluster to a specific version directly.

Expected behavior:
Upgrade the Neptune database using a Blue/Green strategy to test and promote the updated cluster.
