Congratulations on your promotion to the top tier. You will have already gained the skills required to play this game well, it's just a matter of getting used to the extra distance.
The one tip I would give you is to give the correct use of spin greater thought. Don't just hit everything into the greens with full back spin. It's particularly important on the longer shots into the green, don't be afraid to hit your approaches into the greens with one club less, with no spin or a bit of top.
