When moving your data and services from one {{es}} cluster to another, such as to {{ech}}, {{ece}}, new on-premises hardware, or any other {{es}} environment, you can use incremental snapshots to minimize downtime.

* **Network overhead** – Transferring snapshots across networks, regions, or providers can be time consuming and incur costs.
