+# Switch to EF Core Oracle Provider
+
+This document explains how to switch to the **Oracle** database provider for **[the application startup template](Startup-Templates/Application.md)** which comes with SQL Server provider pre-configured.
+
+> This document uses a paid library of [Devart](https://www.devart.com/dotconnect/oracle/) company, because it is the only library for Oracle that supports EF Core 3.x.
+
+## Replace the Volo.Abp.EntityFrameworkCore.SqlServer Package
+
+`.EntityFrameworkCore` project in the solution depends on the [Volo.Abp.EntityFrameworkCore.SqlServer](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.SqlServer) NuGet package. Remove this package and add the same version of the [Volo.Abp.EntityFrameworkCore.Oracle.Devart](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.Oracle.Devart) package.
+
+## Replace the Module Dependency
+
+Find ***YourProjectName*EntityFrameworkCoreModule** class inside the `.EntityFrameworkCore` project, remove `typeof(AbpEntityFrameworkCoreSqlServerModule)` from the `DependsOn` attribute, add `typeof(AbpEntityFrameworkCoreOracleDevartModule)` (also replace `using Volo.Abp.EntityFrameworkCore.SqlServer;` with `using Volo.Abp.EntityFrameworkCore.Oracle.Devart;`).
+
+## UseOracle()
+
+Find `UseSqlServer()` calls in your solution, replace with `UseOracle()`. Check the following files:
+
+* *YourProjectName*EntityFrameworkCoreModule.cs inside the `.EntityFrameworkCore` project.
+* *YourProjectName*MigrationsDbContextFactory.cs inside the `.EntityFrameworkCore.DbMigrations` project.
+
+> Depending on your solution structure, you may find more code files need to be changed.
+
+## Change the Connection Strings
+
+Oracle connection strings are different than SQL Server connection strings. So, check all `appsettings.json` files in your solution and replace the connection strings inside them. See the [connectionstrings.com]( https://www.connectionstrings.com/mysql/ ) for details of Oracle connection string options.
+
+You typically will change the `appsettings.json` inside the `.DbMigrator` and `.Web` projects, but it depends on your solution structure.
+
+## Re-Generate the Migrations
+
+The startup template uses [Entity Framework Core's Code First Migrations](https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/). EF Core Migrations depend on the selected DBMS provider. So, changing the DBMS provider will cause the migration fails.
+
+* Delete the Migrations folder under the `.EntityFrameworkCore.DbMigrations` project and re-build the solution.
+* Run `Add-Migration "Initial"` on the Package Manager Console (select the `.DbMigrator`  (or `.Web`) project as the startup project in the Solution Explorer and select the `.EntityFrameworkCore.DbMigrations` project as the default project in the Package Manager Console).
+
+This will create a database migration with all database objects (tables) configured.
+
+Run the `.DbMigrator` project to create the database and seed the initial data.
+
+## Run the Application
+
+It is ready. Just run the application and enjoy coding.

 However, you can configure your DBMS provider **without** these integration packages. While using the integration package is always recommended (it also makes standard for the depended version across different modules), you can do it manually if there is no integration package for your DBMS provider.
