Hello, this is part of the update process and very easy. In Freelance 2013 do an export of your current project to a CSV file. Then install Freelance 2019 on your Engineering PC and Import your CSV file from the 2013 export. This will create a project in Freelance 2019 with all your programs. Do a check all and the project is ready for download.
I do not list all the steps of updating a system here. That is described in detail (Engineering Station, Operator Station, Controller) in the" Getting started" manual
