Mitigating IT Service Disruptions in Cloud Migration - CGEIT Exam Solution

C.

The most important step that an enterprise should take first when planning to migrate its IT infrastructure to a cloud-based solution is to engage an experienced IT consultant to perform the migration. Therefore, option D is the correct answer.

Migrating to a cloud-based solution can be complex and involves significant changes to an organization's IT infrastructure, operations, and security. Without sufficient experience, an enterprise may face significant risks and potential service disruptions. Engaging an experienced IT consultant can help reduce these risks and ensure that the migration is performed smoothly and effectively.

Option A, evaluating sourcing options, is an important step in the migration process but should come after engaging an IT consultant. The consultant can help the enterprise evaluate the different sourcing options and choose the one that best fits its needs and requirements.

Option B, reflecting the change in the enterprise architecture (EA), is also an important step but should come after engaging an IT consultant. The consultant can help the enterprise assess its current EA and develop a plan to modify it as needed to support the migration.

Option C, implementing key performance indicators (KPIs), is an important step but should come after the migration is completed. KPIs can help the enterprise monitor the performance of its cloud-based solution and identify areas for improvement. However, they are not directly related to reducing the risk of IT service disruptions during the migration process.
