Answer-first summary for fast verification
Answer: Stop the instance; change the instance type to a compute-optimized instance; start the instance.
To change instance type, especially from burstable t3 to compute optimized like c5, the instance must be stopped first. You can't change type while running for most families. Hibernation for stop but not necessary. VM Import/Export is for migration not type change.
