Payroll Premier Data Export to Reckon Accounts

We have a client that wants to stop using Payroll Premier 2016-17 and start using the integrated payroll software in Reckon Accounts Enterprise. Is it possible to export all of the employee information, payroll settings etc from Payroll Premier to Reckon Accounts in one simple step or do we have to do it manually?

I have already looked at the Activities -> Export -> Payroll Data to Reckon Accounts option, however this only brings in opening payroll balances and very basic employee details.

I understand I could be asking for too much here, but thought I may as well ask before we go ahead and start manually entering information for the client (and ultimately charging them for it).

Thanks in advance.
