I will answer this myself also ... So, I talked with the department and I they will not require a new set of documents and medicals ... so at least that's good!
Thanks mate, invaluable advise, I was gonna do the same. I am changing from 885 application to RSMS as well, now I know, it will have to be 119, so my question is because I paid for 885 about $2500, will my 119 be considered a fee-free application...Or will I have to suck in and pay the $2500 for 119...I wont need to pay for the 2nd installment as I have IELTS 8+...Thanks.
