Default Two beers one fermentor = Cross contamination of yeast

Soon i will be transferring a beer out of my fermentor and then another one into it on the same day. I am a little worried that the "old yeast" will get mixed into the new beer.

My sanitation process is going to be as followed. Rinse out the trub with hot water. This will be done twice maybe 3 times. Then i will be filling the fermentor with about 2 gallons of starsan and shake that up a bit. Lastly i will drain the starsan leaving some foam in the fermentor.

Should i be worried???

You should also clean the fermentor with oxyclean or pbw before you sanitize. This ensures that the fermenter is clean, star san will ensure it is sanitized.
