Hi,

First, I recommend you migrate from 2.1 to 2.2 then from 2.2 to 3.0. The last step from 3.0 to 3.1 is very easy.

most of the changes are in program, and startup and package (nuget). just make a new 3.1 project and copy the file contents of these. add any packages you use to the template project first. check the docs of you packs to see if the updates have any changes for startup.

I agree with you, since there are many complications to apply changes on the same solution. In addition of this, I think it's better to make it now and not later on, specially if the solution does not use a large number of dependencies and is going to grow up in the future.

If I was in place of you then I would have starting this by making a new project in ASP.NET Core 3.1 and then transferring my old website to it one part at a time. Moreover ASP.NET Core 3.1 has a new feature of Endpoint Routing which is a new thing to look for. The rest things are not that much important, I think you will not have to do much changes to make your project work in 3.1.
