After much digging in the Sage KB I found this:
Once the test upgrade is completed and the final data migration is performed (again ensuring that all Sage 2018 Product Updates and Payroll Updates are installed in the Live installation), it is recommended that all companies are converted; both live companies and payroll backup companies.
If you desire to access the data in the payroll backup, they will need to be converted and all the steps performed in the live companies will need to be performed in the payroll backup companies.
At your discretion, you can choose to convert payroll backup companies on an as needed basis, but it is important to understand that it is not always possible to remigrate the data should the resolution call for remigration. ID:93930Last Modified Date:6-10-2019
