I clearly can remember the time I'd faced with .net for the first. The most frightening part of .net 2001 was its IDE which induced I'd never ever able to work with. Thanks to some of my strict profs I forced to learn .Net and after awhile found out it was easier than it showed!
Thinks to Gigapedia, one of the lightening direct way to migrate from VB to VB.Net is available to all. I think "Upgrading Microsoft Visual Basic 6.0 to Microsoft Visual Basic .NET" (IFILE.IT) and also MSDN.
Enjoy;D!
