OCI 1Z0-1123-25 Guide: OCI Migration Architect Associate

OCI 1Z0-1123-25 exam guide covering assessments, landing zones, cutover planning, and workload movement decisions.

1Z0-1123-25 is a sequencing-and-cutover exam. Strong answers usually come from choosing the right migration path, dependency order, and connectivity model instead of focusing only on the destination service.

Cutover: The planned point where production traffic or operational responsibility shifts from the old environment to the new one.

Staging: A temporary holding or preparation step used before the final workload move or production switch.

What this guide emphasizes

  • migration planning, dependency mapping, and cutover reasoning
  • connectivity choices such as VCN design and FastConnect
  • database migration and transfer-tool boundaries
  • common exam traps around sequencing, rollback, and data movement assumptions

What strong answers usually do

  • identify whether the issue is connectivity, data transfer, database migration, or cutover control
  • choose the least disruptive path that still meets scale and downtime constraints
  • separate preparation, transfer, validation, and cutover as distinct phases
  • prefer answers that preserve rollback options and operational visibility
