Take a utility network offline

The following code takes a web map offline that contains a utility network. The utility network tables are automatically synced with a map when a utility network is detected within.

The following code takes a utility network offline using a service geodatabase. The utility network tables only get synced when the sync mode in the generate geodatabase parameters is set to sync system tables.
