How can I switch to HDFC SKY?

How can I switch to HDFC SKY?

To initiate the switch, you first need to close your HDFC Securities account. You can do this online by visiting the HDFC Securities e-closure
If your demat account is with HDFC Securities Ltd., it's important to note that using the e-closure link will result in the closure of both your trading and demat accounts if there are no demat balance, negative balances, open positions, or pending orders associated with the client's account. 
If there is balance in your HDFC Securities demat account, then only trading account closure request will be processed and once your HDFC SKY account is opened you need to process the closure of your demat account and transfer of securities in SKY demat by submitting physical “Demat closure cum transfer form”  
You also have the convenient option to only transfer your holdings from your existing HDFC Securities Ltd. demat account to your HDFC SKY demat account via the "CDSL Easiest" method. 
On the other hand, if your demat account is with HDFC Bank Ltd., the closure request will exclusively apply to your trading account. For demat account closure, please reach out to the nearest HDFC Bank demat servicing branch.
