Keep in mind that some won’t and probably should not move their apps. If I had a large web app that was working fine and was likely to reach the end of its life in the next 5 years, moving it to Web Framework 2.0 would not be an attractive option. However, if I didn’t know how long it would be in use and liked some of the benefits of Web Framework 2.0, I’d be considering it.
IF you are one of these folks that should not (Geoffs advice) then your options really are sucky since you cant use the latest version (no web 1.0 in it) and are stuck with using an older vesrion which will NEVER get any more fixes.
