OCI Migration Architect Pro study guide
OCI Migration Architect Pro · Work through your exam, one topic at a time.
The Oracle Cloud Infrastructure Migration Architect Professional credential is aimed at architects and senior engineers who plan and execute moves of workloads from on-premises data centers or other clouds onto OCI. It tests design judgment rather than button-clicking: how you assess an estate, sequence waves, design a landing zone with compartments and identity federation, choose between compute rehosting and replatforming, and migrate Oracle databases to Autonomous Database, Base Database, or Exadata. The OCI Migration Architect Pro study guide has 7 sections and about 2,597 words.
01Migration Strategy, Assessment, and Planning
This domain covers building the case and the plan: inventorying the estate, choosing a migration pattern per workload, sizing targets, sequencing waves, and defining success measures. Questions test whether you pick the right OCI tool for discovery and assessment and can justify the pattern you chose.
399 words, about 2 min02Landing Zone, Identity, and Governance Design for Migration
Landing zone design: tenancy and compartment hierarchy, identity domains and federation, IAM policy structure, network topology, and guardrails such as Cloud Guard, Security Zones, budgets, and quotas. The exam checks that the target tenancy can absorb migrated workloads without redesign later.
401 words, about 2 min03Compute and Application Migration
Shapes, images, and the mechanics of moving applications: agent-based replication with OCI Cloud Migrations, VMware workloads on Oracle Cloud VMware Solution (OCVS), containers to OKE, and how licensing affects the choice of target. Shapes: VM (flexible OCPU/memory), bare metal (dedicated, high core count), and GPU.
374 words, about 2 min04Database Migration to OCI (Autonomous Database, Base Database, Exadata)
Choosing and executing the right Oracle Database migration method across targets: Base Database Service, Exadata Database Service, and Autonomous Database. Expect questions on Zero Downtime Migration (ZDM), Data Pump, GoldenGate, RMAN, transportable tablespaces, and character-set conversion.
357 words, about 2 min05Storage and Data Transfer Options
Matching data to the right OCI storage service and the right transfer path - online versus offline - including the bandwidth arithmetic that decides between them. Object Storage holds unstructured data, backups, and migration staging; tiers are Standard, Infrequent Access, and Archive, with lifecycle policies moving data between them.
361 words, about 2 min06Networking and Connectivity for Migration
How on-premises networks connect to OCI during and after migration: VCN constructs, Site-to-Site VPN versus FastConnect, DRG transit, IP address overlap, and DNS cutover mechanics. VCN building blocks: subnets, route tables, security lists, NSGs, Internet Gateway for public ingress, NAT Gateway for egress, Service Gateway for OCI services without internet traversal.
354 words, about 2 min07Migration Cutover, Validation, and Post-Migration Operations
The execution discipline after planning: runbooks, freeze windows, rehearsal, validation criteria, rollback triggers, and the operational setup that keeps migrated workloads healthy and cost-controlled. A runbook lists each step with an owner, duration, expected result, and a rollback action.
