Changing of the inventory system

Dear Team , Would like to know if there is any process to change the inventory system from perpetual or Periodic inventory for the existing entries ?

If you want to disable perpetual inventory, you can do that from Accounts Settings → Make Accounting Entry For Every Stock Movement.

After disabling you have to set temporary account (Stock Received but not Billed) balance to zero via Journal Entry.

@nabinhait unable to find in Accounts setting.
