Prerequisites for Using the Exadata Cloud Infrastructure Migration Automation Utility

  1. Create or use an existing user.

    For more information on how to create a new user, see Creating a User.

  2. Add the user to a group

    For more information, see Adding a User to a Group.

  3. Assign the following IAM policies by specifying the user's group name and compartment name.
    Allow group '<group name>' to use database-family in compartment <compartment name>
Allow group '<group name>' to use virtual-network-family in compartment <compartment name>
Allow group '<group name>' to manage db-nodes in compartment <compartment name>
Allow group '<group name>' to manage db-homes in compartment <compartment name>
Allow group '<group name>' to manage databases in compartment <compartment name>
Allow group '<group name>' to manage database-software-image in compartment <compartment name>
Allow group '<group name>' to use compartments in compartment <compartment name>
Allow group '<group name>' to use resource-availability in compartment <compartment name>
    Additionally, assign the following policies to ExaDB-D only:
    Allow group '<group name>' to manage cloud-exadata-infrastructures in compartment <compartment name>
Allow group '<group name>' to manage cloud-vmclusters in compartment <compartment name>

    Additionally, assign the following policies to ExaDB-C@C only

    Allow group '<group name>' to manage exadata-infrastructures in compartment <compartment name>
Allow group '<group name>' to manage vmclusters in compartment <compartment name>

    Note:

    If the target is in a different compartment from the source, assign the above policies to the target compartment as well.

    For more information, see Create Identity and Access Management (IAM) Groups and Policies for IAM Users.

  4. To use the OCI SDK for Java, configure the key pair for the user. This key pair is used to authenticate API requests.
    For more information, see:
  5. Setup Virtual Cloud Network (VCN).
    1. The existing VCN may be used if the target is in the same region or compartment as the source.
    2. If the requirement is to use a new VCN or the target is going to be in cross region, then a new VCN setup is required.
      1. The new VCN must have a sufficient number of IP addresses available for creating the VM cluster.

        For more information, see Requirements for IP Address Space.

      2. Ensure that the new VCN has required security lists or rules configured as same as the source VCN.
      3. For setting up Oracle Data Guard, ensure that the connectivity between the source and the target VCNs is established and if a new VCN is to be used, then ensure that the peering is done for the two VCNs allowing the Data Guard association communication.
  6. Request Service Limits and ensure that sufficient resources are available.

    For more information, see Request a Service Limit Increase.

  7. This utility can be run from any Linux x86-64 machine that can make API calls.

    Supported client machine OS version: Oracle Linux 7, Oracle Linux 8, and Oracle Linux 9.

  8. Port requirement

    To make API calls to OCI endpoints ensure that the port 443 (egress) is opened for outgoing connections from the client machine.
