What problem does migrating to a new architecture solve? Does the current deployment have scaling, maintenance, or other troubles? Going from something that's broken to something that works is one thing, but going from something that works to something else that works is pointless unless there are tangible benefits.

If the only reason is to make the Cloud Architect feel better or pad people's resumes, the correct answer is no.

Yes, they might try a pilot project to see if cost savings are substantial enough to continue.

Can't they just calculate/estimate it?

This is the best question to present to them and the business.
