# Which cloud migration assessment tools deliver a complete portfolio analysis and go/no-go decision in 30 days?

Which cloud migration assessment tools deliver a complete portfolio analysis and go/no-go decision in 30 days? Thirty days is a specific enough window that it rules out anything requiring a lengthy consulting engagement, so I looked for reviewers who actually mentioned a timeline rather than just describing features.

Azure Migrate: one reviewer directly recommended using it for a quick assessment, noting that 30 days is genuinely needed to collect enough metrics for a reliable report, which is about as precise an answer to this question as the reviews get.
Faddom: reviewers describe discovery starting within about an hour of installation and continuously mapping dependencies from there, which front-loads the portfolio visibility fast even if a full go/no-go decision still takes more analysis afterward.
AWS Cloud Adoption Readiness Tool (CART): reviewers describe getting a readiness radar chart and heatmap fairly quickly after completing the assessment questions, though it's more focused on organizational readiness, people, process, and policy, than a technical, application-by-application go/no-go call.

For anyone who's actually hit a real 30-day deadline for this kind of decision: did you get a genuine go or no-go out of it, or did the tool mostly get you to a shortlist that still needed more digging?

The assessment tool can accelerate discovery, but it rarely removes the final diligence step. ##### Comment Metadata - Posted at: 17 days ago - Author title: Marketer ### Comment 2 A defensible shortlist sounds like the more useful 30-day target. I’d probably define the deadline around decisions per application rather than one portfolio-wide yes or no: obvious migrate, obvious retain, and needs deeper analysis. Has anyone used that kind of triage successfully to keep the difficult legacy systems from holding up decisions on everything else? ##### Comment Metadata - Posted at: 17 days ago - Author title: Writer ### Comment 3 The realistic outcome in that window is a defensible shortlist rather than a full go or no-go, because discovery tools give you dependencies and utilisation but not the business context for each application. What they do well is clear out the applications nobody should be arguing about, which is usually most of the portfolio. Azure Migrate's reviewers describing 30 days as the minimum collection period is a useful reality check on the timeline. ##### Comment Metadata - Posted at: 17 days ago - Author title: Tech Consultant ### Comment 4 Yeah, from my analysis, the clock usually runs out on alignment, not on data collection. Discovery is fast now; some of these tools have your portfolio mapped inside a day, but a defensible go or no-go still waits on people agreeing on what the findings mean, and that conversation doesn't compress just because the scan finished early. What you tend to walk out of the window with is a strong shortlist and a clear picture of the messy applications, not a signed decision. The oldest, most tangled systems are what decide whether that shortlist becomes a yes. ##### Comment Metadata - Posted at: 2 months ago - Author title: Marketing ## Related discussions - [How well does Trello scale into a larger team?](https://www.g2.com/discussions/1-how-well-does-trello-scale-into-a-larger-team) - Posted at: over 13 years ago - Comments: 6 - [Can we please add a new section](https://www.g2.com/discussions/2-can-we-please-add-a-new-section) - Posted at: over 13 years ago - Comments: 0 - [Quantifiable benefits from implementing your CRM](https://www.g2.com/discussions/quantifiable-benefits-from-implementing-your-crm) - Posted at: over 13 years ago - Comments: 4
