ef-migrations

I have been using EF migrations for some time now and have more than 100 migration files in my project. I would like to consolidate these into a single migration before moving forward - ie I want to replace the existing InitialCreate migration with a new version that takes all my subsequent changes into account so I can then delete all the other migration files. I do this very easily if I am not concerned with losing all the data in the DB, but I am. How can I achieve this whilst keeping all data intact and also retaining the ability to recreate the database from scratch (without data) by just

I can use package manager to run 'update-database -verbose' locally. Probably a stupid question but I can't find it online - once my website is deployed - how can I run this manually on the server? Secondarily - what other strategies would you recommend for deploying database migrations to production - and how would they be preferable? Thanks amhed You have a couple of options: You could use update-database -script to generate the SQL commands to update the database on the server You could use the migrate.exe executable file that resides in the package folder on /packages/EntityFramework5.0.0

Code First Environment I'm trying to update the database from package Manager console.If my Domain class change, I have to drop and create the database,Instead of dropping the Database how can i update the database.

By default, the add-migration command attempts to create the migration .cs file in Project Root Migrations I'd like to store my migrations along with the rest of my EF-related code in the \Data folder of my project: Project Root Data Migrations With this structure, when I execute PM> add-migration Migration1 in the NuGet console I receive the following error: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\MyProjectRoot\Migrations\201112171635110_Migration1.cs'. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init

I'm trying to update a model, but get the error "The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted." From what I understand from The relationship could not be changed because one or more of the foreign-key properties is non-nullable

I've got a Solution with many projects. One of them ( Domain ) is a .NET Standard 2.0 project where I made my EF Core DbContext implementation for which I want to enable database migrations . I saw various blogs and Q/A forums where the problem was explained but none of the proposed solutions seem to work for me because of the .NET Core newer version or (probably) for my particular solution configuration. Solution projects Engine (.NET Core 2.1 Console App) Web API (.NET Core 2.1 Library) Application (.NET Core 2.1 Library) Domain (.NET Standard 2.0 Library) WindowsService (.NET Core 2.1

I have a website and a windows service that both reference the same project to get an Entity Framework data context. Each time I start the windows service, Entity Framework runs an automatic migration that changes one of the database columns from NOT NULL to NULL (no other changes are made). The property for that column is marked as [Required], and the website (which points to the exact same version of the exact same DLL for its model), properly thinks that the database should be NOT NULL for that column. I tried disabling automatic migrations and, as expected, the service then crashed because
