HI..I need to move ProSeries 2019 from my C drive to my D drive.  If I merely move the ProWin19 folder from C to D I get error messages when I open it.  I'm thinking I could follow the instructions you detail for moving from an old computer to a new one.  I'll backup the client files and make a copy of the common folder, then delete ProSeries 2019 from the computer (C drive) and reinstall it on the D drive, then restore the clients and copy the COMMON folder to the new installation then update e-file acknowledgements.  You think that will do it?

Many thanks...

Tom
