I had asked this question about a year ago but I have to revisit again and see if anyone had anything to add.

I have an application to convert from Clipper to FoxPro. Can someone give me some insight or steps /pitfalls to watch for.

Not ever using Clipper, but seeing it all around me as I stayed with Fox despite lots of grief, I can't comment directly to Clipper except to say it is not too far unlike older FoxBASE and non-Windows text-based FoxPro.  Yes, there is the tBrowse in Clipper that isn't in Fox.  Of course, VFP now has grid objects I use fairly often.

Realistically, you'll want to redesign the screens (now Forms) in the visual Form Designer within Visual FoxPro.  And you'll probably want to do the same with reports and use SQL SELECT statements to create snapshots of data that the reports can use without worrying about the source data changing with other user changes.  SET FILTER can also ne a thing of the past with proper use of SQL SELECTs.  Learn SQL SELECT statements to get the most out of VFP that wasn't in old xBASE flavors.

When MS wanted users to switch from FoxPro to Visual FoxPro, they published this that may be of help:

Also, you'll want to take advantage of the OOP that has been in VFP since its release in 1995:
