4 Complete the Post-Migration Tasks

After successfully migrating your Oracle Java Cloud Service instances from Oracle Cloud Infrastructure Classic to Oracle Cloud Infrastructure, test your applications thoroughly, and then perform cleanup and other optional configuration tasks.

Topics:

Test the Target Instance

Verify that your Java applications and other Oracle WebLogic Server resources are accessible and function correctly on the target Oracle Java Cloud Service instance.

Be sure to thoroughly run all application test cases. Also verify that you can access the WebLogic Server Administration Console.

If your instance includes custom data sources that access your application databases, you can test database connectivity directly from the WebLogic Server Administration Console. Select a data source, click the Monitoring tab, and then click the Testing tab.

Migrate FastConnect and VPN Connections to Oracle Cloud Infrastructure

Use Oracle Cloud Infrastructure to create a connection between your private, on-premises network and a network in Oracle Cloud.

A Virtual Private Network (VPN) uses a public network to create a secure connection between two private networks. Oracle supports two connectivity solutions for a Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure:

  • Oracle Cloud Infrastructure FastConnect - Create dedicated, high-speed, virtual circuits for production systems that communicate with your on-premises network using the Border Gateway Protocol (BGP). This service is equivalent to Oracle Cloud Infrastructure FastConnect Classic.
  • IPSec VPN - Create secure connections with your on-premises network using the IPSec protocol. This solution replaces VPN as a Service (VPNaaS) and Corente in Oracle Cloud Infrastructure Classic.

When migrating from Oracle Cloud Infrastructure Classic, update the existing BGP or VPN configuration in your on-premises network to use either Oracle Cloud Infrastructure FastConnect or IPSec VPN. Alternatively, if you require connectivity to instances in both Oracle Cloud Infrastructure and Oracle Cloud Infrastructure Classic during the migration process, create a separate BGP or VPN configuration in your on-premises network.

In Oracle Cloud Infrastructure, creating a connection to your on-premises network includes these tasks:

  • Create a Dynamic Routing Gateway (DRG) in the VCN.
  • Create a route table in the VCN that directs external traffic to the DRG.
  • Assign the route table to a subnet in the VCN.

Refer to these topics in the Oracle Cloud Infrastructure documentation:

Clean Up Resources in Oracle Cloud Infrastructure Classic

After testing your target Oracle Java Cloud Service instance, you can delete the source instance and supporting cloud resources in Oracle Cloud Infrastructure Classic.

Delete these Oracle Cloud Infrastructure Classic resources to avoid costs for services that you no longer use.

  1. Access the Oracle Java Cloud Service console.
  2. Delete the source Oracle Java Cloud Service instances that you created in Oracle Cloud Infrastructure Classic.
    1. Click Manage this instance menu icon for the service instance, and then select Delete.
    2. Enter the Database Administrator User Name and Database Administrator User Password for the infrastructure schema database.
      Alternatively, select Force Delete if you plan to delete this database as well.
    3. Click Delete.
  3. Click IP Reservations.
  4. Delete any IP reservations that you created for your source Oracle Java Cloud Service instances.
    1. Click Delete delete icon for the IP reservation.
    2. When prompted for confirmation, click OK.
  5. Access the Oracle Database Cloud Service console (Database Classic).
  6. Delete the Oracle Database Cloud Service instances that you created in Oracle Cloud Infrastructure Classic to support your source Oracle Java Cloud Service instances.
    Do not delete a database if it is still in use by other services.
    1. Click Manage this instance menu icon for the database instance, and then select Delete.
    2. When prompted for confirmation, click Delete.
  7. Click IP Reservations.
  8. Delete any IP reservations that you created for your Oracle Database Cloud Service instances.
    1. Click Delete delete icon for the IP reservation.
    2. When prompted for confirmation, click OK.
  9. Access the Oracle Cloud Infrastructure Object Storage Classic console (Storage Classic).
  10. Delete the object storage containers that you created in Oracle Cloud Infrastructure Classic to support your source Oracle Java Cloud Service instances.
    Do not delete a container if it is still in use by other services.
    1. Click the delete icon delete icon for the container.
    2. When prompted for confirmation, click OK.
