Yes I will have to purchase 2 additional licenses. I am thinking about adding the two older servers (although the mhz doesnt quite meet min. speeds) to the array and then in august removing one server from the array, adding the new server and then removing the last old server from the array. This should work if im not mistaken.. i will definately research this more but that seems to me the most logical way to go about this issue. Thanks for the timely response and Im gonna start building the first server for the array tonight I think. Thanks again!
