CloudBolt can orchestrate via scripts necessary to convert images amongst formats and transfer. Also supports integration with 3rd Party Tools such as CloudEndure. Integration with Cloud Endure considered preferred approach for Cloud 2 Cloud.
While CB provides the capability to do so it comes with additional effort due to the requirement for scripting or 3rd party integration (additional cost for migrations).
