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.

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.
