1Z0-997-25 Question 144
Single answerYour company needs to migrate a set of on-premises virtual machines (running both Linux and Windows) to Oracle Cloud Infrastructure (OCI). You want to use Oracle Cloud Migrations to automate discovery, schedule replication, and perform a final cutover with minimal downtime. Which approach should you implement to achieve your goals?
- A
Deploy the Oracle Cloud Migrations agent on each source VM, configure block-level replication to OCI, and perform a coordinated cutover after syncing incremental changes.
- B
Export all on-premises disk images to an NFS share, upload them manually to an OCI Object Storage bucket, and then create custom boot volumes from these images.
- C
Set up a third-party snapshot replication tool independent of OCI and synchronize the full dataset before using Oracle Cloud Migrations for discovery only.
- D
Shut down the VMs on-premises, create a backup using Oracle RMAN, and manually restore the backup onto a new Compute instance in OCI.
Show answer and explanation
Correct answer: A
Explanation
Oracle Cloud Migrations provides agents for source VMs to facilitate discovery, replication, and automated cutover. By deploying these agents and using block-level replication, you minimize downtime and simplify the transition to OCI. For more details, refer to the official Oracle Cloud Migrations documentation, which outlines how to configure incremental sync, plan maintenance windows, and orchestrate the final cutover.
- A. Correct.
Correct. This approach aligns with Oracle Cloud Migrations best practices: install the agent on each source VM, configure incremental replication to OCI, and orchestrate the cutover through the Oracle Cloud Migrations service. This method automates discovery, reduces downtime, and ensures a seamless switchover.
- B. Incorrect.
Incorrect. While exporting disk images to Object Storage is a possible migration method, it lacks the automated orchestration, incremental replication, and minimal downtime features offered by Oracle Cloud Migrations.
- C. Incorrect.
Incorrect. Using a third-party snapshot replication tool can complicate the migration process and limit Oracle Cloud Migrations� ability to manage incremental sync and finalize the cutover. Oracle Cloud Migrations is designed for end-to-end migrations, including discovery and replication.
- D. Incorrect.
Incorrect. Shutting down the VMs for a manual backup and restore process disrupts normal operations and does not leverage the incremental replication or automated cutover capabilities of Oracle Cloud Migrations.
