When I upgraded from WIn2016 to Win2019, I copied all backup files of ATX and Payroll from 2013 to the new server. If you have a need to use Payroll from 2015 onwards, you will need to install the software, apply license keys for each year and restore from backup for each year.
I also have PDF copies of all 1099's, W2s and Qtrly reports so no issues.
