+# command will not perform the network automation portions of a QUADS move.
+# Other parts like provisioning, update of host/cloud object fields, IPMI RBAC,

+# Example:
+#   omit_network_move; cloud14, f02-h01-000-r650.example.com, tng.example.com
+# This example would omit all hosts containing any of these values in their address/hostname
+# and also omit network automation portion for any hosts moving to cloud14.
