Sorry if i posted this here, i just need help regarding cloud migration and i don't know where post this.

The company i'm working with right now plans to invest in the cloud, but they don't want to jump in a project that is more than they can handle. I am one of the employees assigned to do this cloud migration thing, as much as possible i want the transition to be smooth and painless. I need tips, strategies or even a practical guide on how to do this. Any help would be greatly appreciated. TIA!
