When I run the following command in package manage console(VS 2019). I get the following error.
Add-Migration InitialMigration
The name 'InitialMigration' is used by an existing migration.

can somebody throw light on this? I am trying to use one project which was used in other machine to learn and tweak this project. Actually this command need to sync database schema and application model classes. At the moment my project doesn't have db - i only have VS files project which was taken from other machine.
i know basic C#, asp.net and a bit of asp.net core.
Cheers
