How to estimate codebase upgrade from .Net framework version 4.6.1 to 4.8

Question

Hi,

I have an existing codebase which runs in production written in .Net version 4.6.1. As per security guidelines, we need to upgrade .Net framework version to 4.8. For that I need to estimate the effort for this activity. How I can do that and what factors may affect the migration like lines of code, number of references added etc.

Thanking you in advance for your guidance.

Regards,

Partha

Do a simple test, copy your project, change .NET version and build to see if error raises

and what factors may affect the migration

For example 3rd part DLL, controls etc.
