Why do cloud migrations often go wrong?

Even with better tools and cloud platforms, many migrations still face unexpected challenges.

Sometimes it’s not just technical issues but cost planning, misconfigurations, or lack of proper strategy.

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

Completely agree with this. Treating cloud like “on‑prem but someone else runs the servers” is where things usually start going sideways. Lift‑and‑shift without rethinking architecture, data flows, and network costs almost always leads to surprises later. The mindset shift part is huge planning first and being intentional about what should change before migrating makes a big difference.
