So that I can bifurcate all the data on financial year basis.

Use Journal Entry. Select Opening Entry. It will pull all balance sheet ledger. Select last year FY closing date. Input DR CR balances. Submit and you will have your last closing as opening for new FY.

If you want P&L information then you need to manually input data. Opening entry will not help. It will be a very tedious manual task.
