ExploreAbout this exam
The Oracle Cloud Infrastructure 2023 Migration Architect Professional credential appears on Oracle University's certification catalog under exam code 1Z0-1123-23. This page is an independent study guide, not an Oracle publication, and makes no claim of affiliation with Oracle or Oracle University. At the time we retrieved the official exam page it returned an HTTP 403 error and displayed only a maintenance notice reading "Our website is currently down for maintenance." Because of that, we cannot state the number of questions, the time limit, the passing score, the exam fee, the delivery format, the retake policy, or how long the credential stays valid; those fields are left blank here rather than filled from memory. The exam is aimed at architects and senior engineers who plan and lead moves of on-premises workloads into OCI, so it rewards breadth: assessment and inventory, landing-zone and network design, database and application migration methods, then cutover and steady-state operations. To prepare, start from Oracle's own exam page once it is reachable, read the official exam objectives, and build hands-on familiarity with the OCI services the objectives name. This guide will be updated when the official page is available again.
What you'll study
About OCI Migration Architect preparation
Is this page run by Oracle or Oracle University?
No. It is an independent study resource. Oracle University's own site is the authoritative place for exam registration, objectives, pricing, and policies. We only describe what we can verify and clearly mark anything we cannot.
Why are the question count, time limit, and passing score missing?
The official exam page returned a 403 error and showed only a maintenance notice when we retrieved it. We do not fill in numbers from memory because exams are revised. Those fields stay empty until the official page states them.
How much does the exam cost and how do I register?
We cannot state the fee because the source did not provide it. Registration is handled through Oracle University and its certification system, not through this site. Check the official exam page or contact your regional Oracle University office for current pricing.
How long is the certification valid, and can I retake the exam?
Neither the validity period nor the retake policy appeared in the source we retrieved, so we do not state either. Oracle's certification policies govern both. Confirm them on the official exam page or with the Oracle certification team before you schedule.
What topics should I study first?
Work in the order a real migration runs: assess the estate and build a business case, design the OCI landing zone and network, choose database and application migration approaches, then plan cutover and operations. Hands-on time with the OCI services named in Oracle's official exam objectives matters more than memorizing trivia.
What is the most common reason candidates struggle?
Treating the exam as a list of product facts. Migration architecture questions usually hinge on trade-offs: which migration method fits a workload, how to sequence cutover, how to keep downtime and rollback risk acceptable. Practice justifying a design decision rather than recalling a feature name.
How should I use practice questions?
Use them to find gaps, not to predict the real exam. After each wrong answer, go back to Oracle's documentation for the service involved and write down why the alternative designs fail. This site's questions are original and are not drawn from any official bank.
Is the 2023 certification still current?
Oracle periodically retires and replaces certification versions. We could not verify the status of the 2023 edition because the official page was unavailable. Check Oracle University for whether this version is still open for registration or has been superseded.
