Simulations at different AoA

I am trying to find out the change of lift coefficient with respect to AoA of an airfoil.
To do this I run the same case but at different Aoa in fluent. All cases start from scratch and iterate till converge.
Today I heard from my friend that I could have run a single case till converge, change the AoA, then continue running that case till converge for new AoA. Will the results be identical and more accurate? This will greatly save a huge amount of time.

If you use the steady flow solver yeah, you can in principle start from any initial solution. So a wise choice will be to do the calculation for say 0 degree, wait until this case converge.
Start a new case with a different AOA say 2 degree but use as initial solution the solution from 0 degree.
For 4 you will use the solution for 2 as initial solution and so on ...
