I don't think this functionality is currently available, however, you can push all your domains into the account with pre-paid funds.

Where can I do this? Do I have to raise a job ticket/order for technical support. Or is this I can do?

While in your account, select the "Domains" tab at the top. Check the box next to "Domain Name" to select all domains in your account. Click "Set Lock" and set to "No". Then, click "Submit". Check the box next to "Domain Name" to select all domains in your account, again. Click "Change Account" and enter the destination Username and Email.
