Select 2You are the lead migration architect for a financial services company preparing to move hundreds of on-premises servers and interdependent applications to Oracle Cloud Infrastructure (OCI) within six months. As part of your discovery and planning phase, you must capture detailed system information, performance metrics, and network dependencies. Which two actions should you prioritize to ensure you have an accurate inventory before performing a detailed migration assessment?
- A
Implement an automated discovery tool to collect server configurations, existing application deployments, and performance metrics across the on-premises environment.
- B
Rely solely on a single spreadsheet of server names and IP addresses maintained by the data center operations team for an initial estimate.
- C
Ignore network connectivity requirements because applications can be reconfigured after migration without impacting the assessment plan.
- D
Map network and application dependencies using agent-based or OS-level commands to identify critical inter-server communication flows.
Show answer and explanation
Correct answers: A, D
Explanation
Prioritizing a thorough discovery and assessment process is essential for a successful OCI migration. Automated inventory tools and structured network mapping are recommended best practices documented in Oracle� migration guidelines. They help identify hidden dependencies, confirm performance baselines, and reduce the risk of overlooking critical applications or services during the migration.
- A. Correct.
Correct. Automated tools reduce human error and provide comprehensive, up-to-date information about your current environment, including resource utilization and application inventory. This data is crucial to making informed migration decisions.
- B. Incorrect.
Incorrect. Relying on a single spreadsheet is a common pitfall. This approach is prone to errors and missing information, which can lead to inaccurate assessments and potential migration failures.
- C. Incorrect.
Incorrect. Network dependencies are critical to ensuring the success of a cloud migration. Overlooking these dependencies often results in connectivity issues, application downtime, or performance bottlenecks once workloads migrate.
- D. Correct.
Correct. Understanding how applications communicate is vital to planning an effective migration strategy. Mapping network flows helps ensure that interdependent services remain available and correctly configured in OCI.
