They are wrong because the inventory is incomplete, assumptions are stale, and the business case changes every time a stakeholder adds context.</p> <p>The AWS Migration &amp; Modernization Blog post on <a href="https://aws.amazon.com/blogs/migration-and-modernization/accelerating-migration-assessments-and-planning-with-aws-transform/">accelerating migration assessments and planning with AWS Transform</a> is interesting because it treats assessment as an interactive workflow instead of a static report.</p> <h2 id="what-changed">What changed</h2> <p>AWS Transform assessments can ingest inventory data from common discovery sources, generate a TCO business case, recommend AWS targets, and then let teams refine assumptions through chat. The source article shows examples such as adding missing servers, adjusting on-premises costs, modeling non-EC2 services, and exploring what-if scenarios.</p> <p>That changes the assessment loop. Instead of recollecting data and regenerating a report for every new question, teams can refine the model conversationally.</p> <h2 id="why-builders-should-care">Why builders should care</h2> <p>Migration planning is full of partial information. A CMDB misses servers. RVTools exports do not capture every cost. Licensing assumptions change. Some workloads are heading to managed services, not EC2. Finance wants a different depreciation model. Application owners remember a dependency late in the process.</p> <p>An interactive assessment tool can keep momentum when those changes happen. That is valuable during early planning, executive conversations, and portfolio prioritization.</p> <p>But the output is only as good as the inputs and assumptions.</p> <h2 id="the-trade-offs">The trade-offs</h2> <p>Conversational planning can make weak assumptions feel more authoritative than they are. A polished business case is still a model.</p> <p>Builders and migration leads should keep three things explicit:</p> <ul> <li><strong>Data source quality:</strong> where inventory came from, when it was collected, and what is missing.</li> <li><strong>Assumptions:</strong> utilization, licensing, storage growth, network costs, support model, and target services.</li> <li><strong>Decision status:</strong> directional estimate, planning baseline, or approved migration wave.</li> </ul> <p>AWS Transform can help generate and adjust the assessment, but it should not replace stakeholder validation. Application owners, finance, security, and operations still need to review the model.</p> <h2 id="what-to-do-next">What to do next</h2> <p>Use AWS Transform early, but label the results honestly. Start with directional estimates, then improve confidence as discovery data gets better.</p> <p>A practical workflow:</p> <ol> <li>Import existing inventory instead of waiting for perfect data.</li> <li>Generate a first-pass business case.</li> <li>Use chat to add known missing costs and workloads.</li> <li>Review assumptions with finance and platform teams.</li> <li>Convert high-confidence groups into migration waves.</li> <li>Reassess after each wave to improve the next one.</li> </ol> <p>The useful takeaway is that migration assessments can become living documents. That is a big improvement over static PDFs, as long as teams keep data quality and assumption ownership visible.</p>
