Ehhhh, I would go to SLX or XT if I was looking at upgrading, I am not really a big fan of just side grading even if I do like Shimano more and would rather have it then SRAM. SX and Deore are basically at the same level(ish) but I might rather put that money towards other upgrades that might make the bike better for me fit/comfort wise or way better shifting and braking.
If you are keeping the same number of speeds you really don't need a new cassette but if your freehub body is an 11 speed freehub body you could swap. If it is XD/XDR then no.
