Migrate Using tar

Use the procedures in this guide to migrate service instances to Oracle WebLogic Server for OCI by using tar.

The following diagram shows the migration topology for a Oracle Java Cloud Service instance. The migration target is a domain created with Oracle WebLogic Server for OCI.

Figure 1-1 Migration Topology

At a high level, the migration process is comprised of these tasks:

1. Create a Oracle WebLogic Server for OCI 12.2.1.4 instance in a private subnet.
2. Verify that the Oracle WebLogic Server for OCI compute instances can access the port to the OCI database used by Oracle Java Cloud Service.
3. Verify that the Oracle WebLogic Server for OCI compute instances can access the ssh port to the Oracle Java Cloud Service instances.
4. Tar the following contents from the Oracle Java Cloud Service instance:
   • /u01/app/oracle/middleware
   • /u01/data/domains
   • /u01/jdk
5. Move the tarballs to the Oracle WebLogic Server for OCI compute instances.
6. Replace the required contents on the Oracle WebLogic Server for OCI compute instances.
7. Replace the host names and database connection strings in the domain with values that point to the Oracle WebLogic Server for OCI host names and OCI database, respectively.
8. If you use Oracle Identity Cloud Service (IDCS):
   • Replace the client id and secret in the IDCS Authentication Provider.
   • Set up the protected paths in the IDCS application gateway.
