Oracle Cloud Migration Deep Dive

Overview

Migrating to OCI from AWS or Azure requires translating IAM concepts (roles to policies, accounts to compartments), networking (VPC to VCN, Security Groups to NSGs), and compute (AMI to custom image). OCI's migration tooling is underdocumented compared to AWS Migration Hub or Azure Migrate. This skill provides comprehensive concept mapping tables, custom image import procedures, network topology translation, IAM policy translation, and data migration patterns — everything needed for a controlled cloud migration.

Purpose: Translate AWS/Azure architecture into OCI equivalents and execute the migration using OCI CLI and Python SDK, with verification at each step.

Prerequisites

• OCI account with an active tenancy — https://cloud.oracle.com
• OCI CLI installed and configured — ~/.oci/config validated (see oraclecloud-install-auth)
• Python 3.8+ with the OCI SDK — pip install oci
• Source cloud CLI — aws CLI or az CLI for exporting resources
• Object Storage bucket in OCI for staging image imports
• IAM policies: manage objects in compartment, manage custom-images in compartment, manage virtual-network-family in compartment
