I have SIP in HDFC top 200 for rs3000, i want to increase the SIP amt to rs5000.i asked MF office they told me to cancel the prev SIP & start a new SIP. i think rather cancelling prev sip n starting new sip can i start 1 more sip for rs 2000 n continue prev sip of rs3000.which option will be better & why?thanks in advance
