I am upgrading all the components on my ATB to XT

question is, do I have to put a new rear hub on the bike as
well made specially for the 9-speed or will the 9-speed
cassette work with my current hub (which has always had a
7-speed cassette on it)? Thanks.

You will need a new Cassette body that is 8/9 speed compatible.

is an article that should help.
The 8/9 speed cassette body comes on a new 8/9 speed compatible hub, but if your existing wheel is in good shape, the cassette body swap may be quite practicle.

Only 8 of the 9 cogs will fit on your 7 speed hub. That's a
fine setup if you don't mind only running 8 cogs. There's no
special technique required, just set the derailer limit
screws properly.
