We are migrating many ASP.NET 1.1 web applications to new servers. We would like to convert all of them to 2.0 in the process. Ideally, in the end, the 1.1 framework will not even be installed on the new servers. We’ve never had major issues converting applications to 2.0 from 1.1. Our biggest issue has always been changing ConfigurationSettings.AppSettings to ConfigurationManager.AppSettings.
Has anyone else ever had major issues?
Are there any major things to look out for or consider up front?
Here is a good resource on how to convert asp.net applications from 1.1 to 2.0 using visual studio 2005.
