Temporary servers for upgrade projects in S/4HANA Cloud private edition

[wjkim]

Hi, all

We are approaching the time when we need to upgrade older version of S/4HANA, and we are considering the best approach.

We understand the scope of services provided by ECS and CAS, but we would like to know about the costs and procedures related to the temporary servers(sandbox system) needed during the upgrade project.

1. If we subscribe to CAS and proceed with the project, does the CAS package include the provision of temporary servers?
2. If we proceed with the project by requesting ECS services only, how do we request temporary servers? Additionally, will there be separate charges for the temporary server usage?

Best Regards,
