Migration Evaluator Duration

The duration of assessments with AWS Migration Evaluator can vary depending on the specific needs and complexity of the organization, but typically follows these timelines:

1. Data Collection: This phase usually takes about 7 days or more. The Migration Evaluator team helps collect on-premises infrastructure data, including server sizing and time-series utilization data. The longer the collection period, the more accurate the results will be.

2. Analysis: Once data collection is complete, the analysis phase begins. This typically takes a few business days for the AWS team to compile the collected data, conduct the analysis, and prepare the results.

3. Results Review: After the analysis is complete, there's a review session where an AWS Solutions Architect walks you through the assessment insights, financial summary, business value, deployment summary, and next steps. This is usually a single meeting, but may require follow-up if changes or clarifications are needed.

Overall, the full process for a Migration Evaluator assessment generally takes between 30 to 45 days from start to finish. This timeline allows for comprehensive data collection, thorough analysis, and a detailed review of the results to help organizations make informed decisions about their AWS migration strategy.

It's worth noting that there are different assessment options available. For instance, a "Lite" version might be quicker if an organization has a VMware-only environment and can provide point-in-time information from VMware vCenter. The full version, which is more comprehensive and suited for mixed environments, typically follows the longer timeline mentioned above.
