Follow this link. This will give some guidance for your migration.
https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-2.2&tabs=visual-studio
As stated in the comments, the complete path of migration from 2.0 to 3.0 would be:
- Migrate from ASP.NET Core 2.0 to 2.1
- Migrate from ASP.NET Core 2.1 to 2.2
- Migrate from ASP.NET Core 2.2 to 3.0...
You will have to go through them step by step.
