>>Just like it did for the million of VB6 programmers? :-))

from VB1 to VB6 there was always a clear migration path.
the jump from VB6 to Visual Studio .NET was the most awkward.
The migration paths from Visual Studio .NET to VS .NET 2003 and then VS 2005 were all clear.

Therefore, out of roughly 10 version upgrades one was somewhat difficult.
Likewise, FPD2.6 to FPW2.6 to VFP3 etc etc... all those version upgrades provided a clear migration path... with the 2.6 to 3 being the most difficult.

In order to take on new challenges (back in 1995 it was Visual, OOP, transactional database processing)... you sometimes have to learn a lot between versions.
