OCI Migration Architect Pro case studies
OCI Migration Architect Pro · Put your knowledge to work in context.
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 case studies are 5 cases and about 5,233 words.
