+# OpenIddict Angular UI Migration Guide
+
+## Angular Project
+
+- In `environment.ts` and `environment.prod.ts` **add a trailing slash at the end of the issuer**:
+
+  ```typescript
+  oAuthConfig: {
+      issuer: 'https://localhost:44377/',
+      ...
+    },
+  ```
+
+## Http.Api.Host (Non-Separated IdentityServer)
+
+- In **MyApplication.HttpApi.Host.csproj** replace **project references**:
+
+  ```csharp
+  <PackageReference Include="Volo.Abp.AspNetCore.Authentication.JwtBearer" Version="6.0.0-rc.1" />
+  <PackageReference Include="Volo.Abp.Account.Web.IdentityServer" Version="6.0.0-rc.1" />
+  ```
+
+  with   
+
+  ```csharp
+  <PackageReference Include="Volo.Abp.Account.Web.OpenIddict" Version="6.0.0-rc.1" />
+  ```
+
+- In the **MyApplicationHttpApiHostModule.cs** replace usings and **module dependencies**:
+
+  ```csharp
+  using System.Net.Http;
+  using Volo.Abp.AspNetCore.Authentication.JwtBearer;
+  ...
+  typeof(AbpAspNetCoreAuthenticationJwtBearerModule),
+  typeof(AbpAccountWebIdentityServerModule),
+  ```
+
+  with 
+
+  ```csharp
+  using OpenIddict.Validation.AspNetCore;
+  ...
+  typeof(AbpAccountWebOpenIddictModule),
+  ```
+
+- In the **MyApplicationHttpApiHostModule.cs** add `PreConfigureServices` like below with your application name as the audience:
+
+  ```csharp
+  public override void PreConfigureServices(ServiceConfigurationContext context)
+  {
+      PreConfigure<OpenIddictBuilder>(builder =>
+      {
+          builder.AddValidation(options =>
+          {
+              options.AddAudiences("MyApplication"); // Replace with your application name
+              options.UseLocalServer();
+              options.UseAspNetCore();
+          });
+      });
+  }
+  ```
+
+- In the **MyApplicationHttpApiHostModule.cs** `ConfigureServices` method, **replace the method call**:
+
+  From `ConfigureAuthentication(context, configuration);` to `ConfigureAuthentication(context);` and update the method as:
+
+  ```csharp
+  private void ConfigureAuthentication(ServiceConfigurationContext context)
+  {
+      context.Services.ForwardIdentityAuthenticationForBearer(OpenIddictValidationAspNetCoreDefaults.AuthenticationScheme);
+  }
+  ```
+
+- In the **MyApplicationHttpApiHostModule.cs** `OnApplicationInitialization` method, **replace the midware**:
+
+  ```csharp
+  app.UseJwtTokenMiddleware();
+  app.UseIdentityServer();
+  ```
+
+  with
+
+  ```
+  app.UseAbpOpenIddictValidation();
+  ```
+
+- In the **MyApplicationHttpApiHostModule.cs** `OnApplicationInitialization` method, delete `c.OAuthClientSecret(configuration["AuthServer:SwaggerClientSecret"]);` in `app.UseAbpSwaggerUI` options configurations which is no longer needed.
+
+- In `appsettings.json` delete **SwaggerClientSecret** from the *AuthServer* section like below:
+
+  ```json
+  "AuthServer": {
+      "Authority": "https://localhost:44345",
+      "RequireHttpsMetadata": "false",
+      "SwaggerClientId": "MyApplication_Swagger"
+  },
+
+## Http.Api.Host (Separated IdentityServer)
+
+- In the **MyApplicationHttpApiHostModule.cs** `OnApplicationInitialization` method, delete `c.OAuthClientSecret(configuration["AuthServer:SwaggerClientSecret"]);` in `app.UseAbpSwaggerUI` options configurations which is no longer needed.
+
+- In `appsettings.json` delete **SwaggerClientSecret** from the *AuthServer* section like below:
+
+  ```json
+  "AuthServer": {
+      "Authority": "https://localhost:44345",
+      "RequireHttpsMetadata": "false",
+      "SwaggerClientId": "MyApplication_Swagger"
+  },
+  ```
+
+## MyApplication.IdentityServer
+
+This project is renamed to **MyApplication.AuthServer** after v6.0.0-rc1. 
+
+- In **MyApplication.IdentityServer.csproj** replace **project references**:
+
+  ```csharp
+  <PackageReference Include="Volo.Abp.Account.Web.IdentityServer" Version="6.0.0-rc.1" />
+  ```
+
+  with   
+
+  ```csharp
+  <PackageReference Include="Volo.Abp.Account.Web.OpenIddict" Version="6.0.0-rc.1" />
+  ```
+
+- In the **MyApplicationIdentityServerModule.cs** replace usings and **module dependencies**:
+
+  ```csharp
+  typeof(AbpAccountWebIdentityServerModule),
+  ```
+
+  with 
+
+  ```csharp
+  typeof(AbpAccountWebOpenIddictModule),
+  ```
+
+- In the **MyApplicationIdentityServerModule.cs** add `PreConfigureServices` like below with your application name as the audience:
+
+  ```csharp
+  public override void PreConfigureServices(ServiceConfigurationContext context)
+  {
+      PreConfigure<OpenIddictBuilder>(builder =>
+      {
+          builder.AddValidation(options =>
+          {
+              options.AddAudiences("MyApplication"); // Replace with your application name
+              options.UseLocalServer();
+              options.UseAspNetCore();
+          });
+      });
+  }
+  ```
