Is the destination environment accessible when refreshing Oracle Field Service environment with the data from another environment?

You can refresh an environment by replacing the existing data of your Oracle Field Service environment with the data from another environment.

When you opt for a refresh, a 24-hour period is utilized for internal operations, during which the destination environment remains fully available. The actual configuration overriding operation will make the instance temporarily unavailable, but this downtime is very brief and typically goes unnoticed by users. Thus, the environment refresh is essentially a near-zero-downtime operation.

However, during the latter half of the refresh operation, the destination environment enters maintenance mode for the database upgrade process. This phase is typically time-consuming, often taking 30 minutes or more to complete. For more information, refer to Refresh from Another Environment.
