Hi muna01
No unfortunately you cannot. The import and export is limited to basic info only in some cases. When i comes to Payroll the only thing you can export/import as the employee cards, their TFN and timesheets, not much else.
Suggest google 'new myox based on existing' or similar - their is a company that can take your existing file and remove all transactions and balances - everything else stays as it was. Costs around $132 which can save you hours of importing and manual entries to get the same thing. You can also delete thing like Items, cards, accounts you no longer need.
