Unposted Batches cleanup from prior fiscal year

Hello,

I am trying to understand better possible approaches in doing some clean up effort on some of Unposted Batches from previous fiscal year ...

after discussing with business, found that they have worked it around these unposted batches entries by breaking down the transactions and by creating JE's in different batches .. and posted those batches successfully ...

for business the books are correct and fiscal year closed and all those stuff are ok ... no issues on balances and financial statements ...

Now the question arises how do we clean up the batches from prior fiscal year that are Unposted and has Batch status E, U, Pending, etc.,
