I was there in those days too. VB was a very beginner-friendly language, more akin to what we call today "low-code" than other languages. Those developers didn't have to "re" learn software development, as you think, instead they probably never knew software development well enough to use languages like VB.NET (which is what all of the VB devs I worked with ended up on). "C# and .NET" is equal to any language you can think of in terms of complexity, so C# devs are going to be just fine.
