Problems updating the site from .net 2.0 to 3.5

I want to upgrade my company website from 2.0 to 3.5. I think this should be pretty painless, since all the old methods are still supported (just depreciate) in newer versions of .net. It is right?

We had no problems updating all our applications from 2.0 to 3.5

I doubt that you will have problems because .NET 3.0 and 3.5 are β€œadditive” versions, which means that the basic functions of .NET 2.0 remain unchanged, they just add functions.

This brief article explains this a bit more clearly: http://www.4guysfromrolla.com/articles/112107-1.aspx

As a side note, we also had no problems with 2.0 right up to 4.0. Microsoft is very good at making updates painless.

I would like to throw a disclaimer - if you use third-party components, I can not vouch for how easily they survive in the upgrade process, but taking into account the additive nature of releases through 3.5. I think you will be fine.
