OCI Migration Architect Pro study plan
OCI Migration Architect Pro · Give each week a clear focus.
8 weeks · About 7 hours per week
Migration Strategy, Assessment, and Planning
Build a migration assessment checklist covering workload discovery, dependency mapping, and business-driver capture
Classify a sample application portfolio into rehost, replatform, refactor, repurchase, retain, and retire buckets
Draft a total-cost-of-ownership comparison template that contrasts on-premises run rate with OCI pricing dimensions
Explain how Oracle Cloud Advisor and Cloud Migration Advisor outputs feed a migration business case
Your checkpoint
A one-page assessment framework plus a completed portfolio classification table for at least 10 hypothetical workloads, with a written rationale for each placement decision
Migration Strategy, Assessment, and Planning
Sequence migration waves by dependency depth, business criticality, and risk tolerance
Define rollback criteria and go/no-go gates for each wave
Estimate effort and duration for a wave using discovery data rather than guesswork
Identify the stakeholders and sign-off authorities needed at each planning stage
Your checkpoint
A wave plan document covering three waves with entry criteria, exit criteria, rollback triggers, and a RACI table
Database Migration to OCI (Autonomous Database, Base Database, Exadata)
Compare Autonomous Database, Base Database Service, and Exadata Database Service on fit, effort, and operational burden
Map Oracle database versions and features to supported target shapes and editions
Plan a migration method per database: Data Pump, GoldenGate, Zero Downtime Migration, or logical extraction
Size a target database from source AWR and capacity data
Your checkpoint
A database migration decision matrix for six sample databases naming the target service, migration tool, downtime window, and sizing basis for each
Database Migration to OCI (Autonomous Database, Base Database, Exadata) & Compute and Application Migration
Design a physical migration runbook for a large database including pre-checks, cutover steps, and validation queries
Configure and validate Oracle GoldenGate replication for a cross-platform scenario in a lab or sandbox
Plan a compute migration for application servers using OS-level tooling or image import
Document application-to-database dependency ordering so compute and database cutovers stay synchronized
Your checkpoint
A combined database and application cutover runbook with timed steps, validation SQL, and a rollback path, reviewed against a peer checklist
Landing Zone, Identity, and Governance Design for Migration & Networking and Connectivity for Migration
Design a landing zone with compartments, tagging, budgets, and policy guardrails that enforce least privilege
Configure identity federation between an enterprise identity provider and OCI IAM, including group-to-policy mapping
Select a connectivity option among FastConnect, site-to-site VPN, and public endpoints for a given latency and throughput requirement
Plan DNS, routing, and security list or NSG rules that survive the cutover
Your checkpoint
A landing zone and connectivity design document with a compartment hierarchy diagram, policy statements, and a connectivity decision table for three scenarios
Storage and Data Transfer Options
Match data transfer methods to dataset size and change rate: Object Storage upload, Data Transfer appliance, FastConnect, or replication
Estimate transfer duration for a given dataset size and available bandwidth, including overhead
Plan storage tiering and lifecycle policies for migrated data
Validate data integrity after transfer using checksums and object inventory comparison
Your checkpoint
A data transfer plan for a 50 TB dataset with method selection, bandwidth math, integrity verification steps, and a lifecycle policy definition
Migration Cutover, Validation, and Post-Migration Operations
Write a cutover checklist covering communications, freeze windows, DNS changes, and smoke tests
Define post-migration validation criteria for application, database, and network layers
Plan a hypercare period with monitoring, alerting, and escalation paths
Identify decommissioning steps and data retention obligations for the source environment
Your checkpoint
A cutover and hypercare playbook with a validation matrix, escalation contacts, and a decommissioning checklist
Migration Strategy, Assessment, and Planning & Landing Zone, Identity, and Governance Design for Migration & Compute and Application Migration & Database Migration to OCI (Autonomous Database, Base Database, Exadata) & Storage and Data Transfer Options & Networking and Connectivity for Migration & Migration Cutover, Validation, and Post-Migration Operations
Synthesize the prior weeks into one end-to-end migration plan for a realistic multi-tier scenario
Audit your own deliverables against each exam domain and close the weakest gaps
Practice explaining trade-offs aloud for architecture decisions you made
Review any facts you flagged as uncertain and confirm or correct them
Your checkpoint
A consolidated end-to-end migration plan document plus a self-assessment gap list naming the two weakest domains and the specific remediation for each
Milestones
Week 2: You can defend a wave sequence and rollback strategy to a skeptical stakeholder without notes
Week 4: Your database decision matrix covers all three target services and you can justify each migration tool choice
Week 6: You can complete bandwidth and transfer-duration math for an arbitrary dataset without reference material
Week 8: The end-to-end plan addresses all seven domains and your gap list contains no unresolved uncertainty
