Hi @sumitshah
You need to add a migration to your project and update the database first. Then, it should be fine.

Hi @sumitshah
You can run "dotnet ef migrations add Upgraded_To_ABP_7_0" (or you can use another migration name) command in the root directory of EntityFramework project. This command will create the migration for you.
Then, you can either run "dotnet ef database update" command or you can run the Migrator project in your solution to update the database.
