Mixing Shimano Parts, possible?

Hey guys, I have a newb question here, i have an old mtb that came with a shimano tourney/sis drivetrain set, i recently discovered that my crankset and cassette are already worn out causing me all the shifting issues that i have been facing, is it possible for me to just change the crankset & cassette to a Deore / Alivo without changing my RD/FD and shifters at the same time?
Thanks,
John

Depending on the crankset you may need to change the bottom bracket as well. Crankset determines axle length and chain line.
