SWM-8 Install Question

I currently have the AU9 antenna and need to connect it to a SWM-8. Currently there are only 3 cables coming out of the arm from the LNB. Two are run into the house and the other is terminated with a cap. I need to remove the LNB to get to the fourth connector to run the four lines to the SWM-8. My question is if I don't disturb the antenna aim during this process will the dish need to be re-aligned after I remove the LNB and reconnect it?

Thanks. I thought I'd tighten all the mounting and adjustment bolts first just to make sure nothing is going to move. I assumed that if the LNB was fastened to the LNB feed arm the same as it was it wouldn't be a problem.
