Backup that client then create a new work directory with that one client. Follow the steps to convert. https://proconnect.intuit.com/community/convert-data-files/help/proseries-backup-instructions-for-da...

Thank you, I followed these steps, however only 2018 was allowed as an option (to convert 2018 to 2019).  How can we convert older files?  I need to prepare a 2016 1065 and have a Prosystems 2015 data file.  Thank you.

Is PTO still available for 2016? I know they cut off some old years. Don't know how far back.
