    hi shobhit

    Identity Server 4 has a lot of breaking changes, have you applied to your project?

    hi

    You can create a new project of version 4.0. Then compare the code.

    If possible you can provide me with a project, I can download and check to it. liming.ma@volosoft.com

    How can I install a specific version of ABP Suite?

    hi

    You can consider deleting all migrations and then adding a new one. You can delete the Migrations folder.

    Please backup the database before trying.

    Re-adding the migration will solve your problem.

    This is a simple way, otherwise I need to get the source code of your project to check.

    Please back up the code and database.

    1. delete the Migrations folder.
    2. run dotnet ef migrations add Initialcommand in xxx.EntityFrameworkCore.DbMigrations folder.
    3. run dotnet ef database update command or run xxx.DbMigrator to apply.

    hi @shobhit

    Can you reproduce the problem in the 4.0 template project? Because I see you are using different connection strings for different modules.

    hi

    I mean can you find some differences between your project and the template project that might be causing the problem.

    That is, if you copy some code of your project to the template project, the above problem occurs.

    Ok.

    So as per suggestion i have created new ABP4.0 project. I run the DBMigrator and it has created the fresh db schema. Now when i am running DBMigrator again it is throwing error:

    [22:26:00 INF] Started database migrations... [22:26:00 INF] Migrating schema for host database...

    The reason for this situation may be that the __EFMigrationsHistory table is empty after the first execution of DBMigrator.

    hi

    Can you check the __EFMigrationsHistory table of the database after you exec the migration? Generally this does not happen.
