Convert Angular.js web frontend from .net 4.6 to .net 5 (which is core)

We have an angular.js frontend for our software which currently works on .net 4.6. We need to run it on a linux server and so we need to upgrade the project. This cannot be done automatically, but we don't need any new functionality. The correct applicant needs to be available to do this this weekend, we have to have it Monday morning. If you've never done this before, now is not the time to try and learn. Please reach out if you have proven experience at this.
