 If you only want to redirect the actual replication data, you just need to re-route all objectstorage traffic via your FastConnect/VPN. IP addresses for your region used by Object Storage are specifically mentioned in the JSON file.

+Steps to configure to ensure OSN traffic is routed over your FastConnect or VPN.
+
+1.	Configure your on-premise router to route all traffic to the Oracle Cloud Service network for your region towards your FastConnect or IPSEC tunnel.
+2.	Create a Route Table inside your VCN that has route rules in place for your on-premise CIDR ranges and route this to your DRG
+3.	Create a Service Gateway
+4.	On your service gateway set a customer route table. This should be set to the route table created in set 2.

 Within a project, you create migration plans. A migration plan is a mapping of VMware virtual machines to target resource types in OCI. A migration plan provides the context to launch virtual machines, including compartment, subnets, and launch dependencies.
 
-The virtual machines are replicated on OCI instances.
+When the replication is completed, we can generate a RMS Stack based on the migration plan. Applying this RMS stack will launch the OCI Compute instances using the replicated disks.
 
 You can mark the project as complete. After a project is marked complete, Oracle Cloud Migrations decouples the production environment from the migration workflow and archives migrated inventory.

 ## Oracle Cloud Migrations Terminologies
 
 Review the following terms to understand the Oracle Cloud Migrations service.
 
-* Agent dependency: Third-party libraries that are required for migration tasks. To comply with licensing terms, you must obtain these libraries separately and make them available to the remote agent appliance.
-
-* Assets: The Oracle Cloud Migrations service works with multiple types of assets including virtual machines and their associated data disks. Assets are categorized depending on the stage of the migration workflow. Refer to the following asset types:
-
-* External asset: The external assets are hosted in an external environment outside Oracle Cloud Infrastructure (OCI). For example, a VMware vSphere environment that is located on-premises.
+* Agent dependency: Third-party libraries that are required for migration tasks. To comply with licensing terms, you must obtain these libraries separately and make them available to the remote agent appliance. (VMware VDDK)
 
 * Inventory asset:  A representation of a resource that exists outside of OCI. These resources contain metadata, metrics, history, and how the physical or virtual entities are discovered and imported. Assets can be added to inventory by running discovery in the source environment, CSV import, or using the API.
