Add-Migration Adds a new migration. Remove-Migration Removes the last migration. Scaffold-DbContext Scaffolds a DbContext and entity type classes for a specified database. Script-Migration Generates a SQL script from migrations.
Delete your Migrations folder. Create a new migration and generate a SQL script for it. In your database, delete all rows from the migrations history table. Insert a single row into the migrations history, to record that the first migration has already been applied, since your tables are already there.
To revert the last applied migration you should (package manager console commands): Revert migration from database: PM> Update-Database <prior-migration-name> Remove migration file from project (or it will be reapplied again on next step) Update model snapshot: PM> Remove-Migration.
Update-Database has a TargetMigration parameter that you can use to update to a particular migration. You can use that to upgrade or downgrade.
