Hi Carmen,
Thank you for your enquiry. You are right, the program does not prompt you to upgrade a file from v19.6 when opened in v19.9 (or v19.7 / 19.8 for that matter), due to the version number (v19) being the same.
This most often will not cause any issues with confirming the file. However if the file were to be opened in v19.9 and then taken back to v19.6 there can be issues caused due to the different Payroll Tax Tables in the two versions.
Therefore it is recommended to open the clients' files using the version that they are registered for, except in situations (as per my suggestion to Helen) where the files are opened using different programs with the same version numbers (Plus v19.6 / Premier v19.6 / Enterprise v19.6).
Regards,
