One question on this - why would family id be needed. PPF would map to the same cust id right.1. You transfer the PPF account to AXIS Directly.
2. Open a Burgundy Savings account in parallel & put 5 Lakh as an initial funding.
3. Once the account is created then first make sure the scheme code is SBPPR. Then create the Family ID with your PPF so that the total balance(PPF+Savings) is shown at a glance(Along with PPF) once you logged in to Axis Mobile Application.
4. Once the Family ID is created & PPF is mapped then you are done, remove all the fund from savings. It will stay there forever.
