And about .NET ???

Ok, some companies are planning the W2k server upgrade but what about the .NET that is comming soon?. Should we start preparing the upgrade from NT to .NET instead of going to W2k first?. Because if we are going to do a mayor change in our server’s OS from NT to W2k and later next year from W2k to .NET would it be better to wait a few months and go directly to .NET?
