1 About Migrating to Oracle Cloud Infrastructure
Learn about migrating Oracle Data Integrator Cloud to Oracle Cloud Infrastructure
Why Migrate to Oracle Cloud Infrastructure
Oracle encourages you to migrate your existing cloud resources from Oracle Cloud Infrastructure Classic regions. You can gain several advantages by doing so.
In Oracle Cloud, you provision resources in specific regions, which are localized to geographic locations. A region supports either the Oracle Cloud Infrastructure Classic or Oracle Cloud Infrastructure platform.
Oracle Cloud Infrastructure is Oracle's more modern infrastructure platform that's based on the latest cloud technologies and standards. It typically provides better performance than Oracle Cloud Infrastructure Classic. Oracle Cloud Infrastructure also has more predictable pricing and lower costs in terms of Oracle Compute Units (OCPUs) per hour. Most importantly, Oracle continues to invest in Oracle Cloud Infrastructure, including the addition of new regions, services, and features. See Data Regions for Platform and Infrastructure Services.
You can benefit from these additional administrative features in Oracle Cloud Infrastructure when you migrate your cloud resources from Oracle Cloud Infrastructure Classic:
- Organize cloud resources into a hierarchy of logical compartments.
- Create fine-grained access policies for each compartment.
About the Migration Scope
Learn about the scope of migrating Oracle Data Integrator Cloud to Oracle Cloud Infrastructure.
This guide focuses on Oracle Data Integrator Cloud to Oracle Service on OCI Classic as the source service. There are two options for the target service. The first is to have Oracle Data Integrator Cloud to Oracle Service running on OCI, the second is Oracle Data Integrator running on a Compute instance.
About Oracle Cloud Infrastructure
Get familiar with basic Oracle Cloud Infrastructure security, network, and storage concepts, and their equivalent concepts in Oracle Cloud Infrastructure Classic.
Cloud resources in Oracle Cloud Infrastructure are created in logical compartments. You also create fine-grained policies to control access to the resources within a compartment.
You create instances within an Oracle Cloud Infrastructure region. You also specify an availability domain (AD), if supported in the selected region. Oracle Cloud Infrastructure Classic does not use availability domains.
A virtual cloud network (VCN) is comprised of one or more subnets, and an instance is assigned to a specific subnet. In Oracle Cloud Infrastructure Classic, you assign instances to IP networks or the shared network. Typically, you create one subnet for the shared network, and create a separate subnet for each IP network in Oracle Cloud Infrastructure Classic. Note that unlike Oracle Cloud Infrastructure Classic, Oracle Cloud Infrastructure does not allow you to reserve IP addresses for platform services.
A subnet's security lists permit and block traffic to and from specific IP addresses and ports. In Oracle Cloud Infrastructure Classic, an instance's access rules provide similar capabilities, although security lists are configured at the subnet level.
Instances can communicate with resources outside of Oracle Cloud by using Oracle Cloud Infrastructure FastConnect, which provides a fast, dedicated connection to your on-premises network. This service is equivalent to Oracle Cloud Infrastructure FastConnect Classic. Alternatively, use IPSec VPN in Oracle Cloud Infrastructure as a replacement for VPN as a Service (VPNaaS) or Corente in Oracle Cloud Infrastructure Classic.
A bucket in Oracle Cloud Infrastructure Object Storage can be used to store files and share them with multiple instances. A user's generated authentication token (auth token) is required to access the bucket. Oracle Cloud Infrastructure Object Storage Classic provides the same service in Oracle Cloud Infrastructure Classic, but does not use auth tokens.

About the Migration Task Flow
Learn about the flow of the task of migrating Oracle Data Integrator Cloud to Oracle Service from OCI Classic to OCI.
- Export the Oracle Data Integrator (ODI) repository meta data from the ODICS instance on OCI Classic.
- Create the target ODICS configuration on OCI, or the target ODI configuration running on a Compute instance.
- Import the (exported) repository meta data exported from step 1 into the target of ODICS on OCI or ODI on Compute.
- Configure the new instance on the target environment.
- Test the new instance.
- Delete the original ODICS instance on OCI-C.
