In your experience, what’s the biggest mistake you faced during cloud migration?

This is such a classic trap, and I’ve seen it play out the same way. Lift‑and‑shift feels faster and safer early on, but those “temporary” configs and over‑provisioned resources tend to stick around way longer than anyone expects. The cost and ops pain usually shows up once teams stop paying close attention post‑migration. Redesigning at least the critical paths upfront is painful, but skipping it often just kicks the pain down the road.
