10 - 9spd Drive train Question

Hey guys im sure this has been asked before but cant find it

Currently my tri and roadbikes have 2005 105 9spd groups on them i want to start slowly migrating to 10speed groups (as 105 is no longer 9spd) but i dont want to drop cash for a full groupo all at once, So here is my Q

Can i change the Rear dearlier of my 9spd 105 group to a 10 speed RD with out changing the Cassette and shifterlevers? should i change to a 10spd chain with that new RD?

9 and 10 RDs are interchangable, mix and match no problem. Same with 9/10 cranks. External bearing cranks are nice, but not required. Spend the inital cash on the brifters and cassette. Replace the rest when they break.

To change from 9 to 10, the minimum you need to get is 10-speed shifter, cassette, and chain. All other parts do not need to be changed.
