Payroll Upgrade v17 to v19 ADV Setups on Final Upgrade from test

Payroll Upgrade v17 to v19 ADV Setups on Final Upgrade - Is there certain files that could be backup-ed up from a completed test upgrade  and then copied back after final migrate to put back all the updated PR setups+ settings / changes for Payroll?  We do plan to make a copy to a backup company code in S100 to preserve it but wondering from time perspective if there is a list of files containing PR setups that could be quickly copied back in from a test pass but not affect the refreshed data.
