Migrating from Duende to SimpleIdServer

If you're currently using Duende IdentityServer version 7, migrating to SimpleIdServer is a smooth and straightforward process. With the help of our migration tool, you can quickly transition your identity server without hassle.

How to Migrate

To begin the migration, you will need to install the SimpleIdServer.IdServer.Migrations.Duende NuGet package on your identity server. This package provides the necessary tools to facilitate the migration from Duende to SimpleIdServer.

cmd.exe

dotnet add package SimpleIdServer.IdServer.Migrations.Duende

Once the NuGet package is installed, follow these steps to configure your migration:

Edit the Program.cs file; Add two essential functions:

• EnableMigration: This function registers the dependencies needed to execute the migration.

• AddDuendeMigration : This function registers the dependencies for migrating data from a Duende database to a SimpleIdServer database. It takes a lambda expression as a parameter, where you can specify the database connection string.

Here's an example of how to configure the migration:

Program.cs

builder.AddSidIdentityServer()
    .EnableMigration()
    .AddDuendeMigration(a =>
    {
        a.UseSqlServer(""); // Add your connection string here
    });

Running the Migration

Once the migration is set up, you can execute it in two ways:

1. Manual Execution via Admin Portal: You can trigger the migration manually by navigating to the Migrations tab in the administration portal of your identity server.

2. Automatic Execution on Server Startup: If you want the migration to run automatically when the identity server starts, you can call the LaunchMigration function. This function takes a parameter, the realm, which determines where the data will be migrated. By default, this value is set to master.

Example :

Program.cs

app.Services.LaunchMigration();

Entities Migrated

The following entities will be migrated from Duende IdentityServer to SimpleIdServer:

Duende Entity	SimpleIdServer Entity
ApiScopes	Scope
IdentityResources	Scope
ApiResource	ApiResource
Client	Client
Groups	Groups
Users	Users

With this migration process, your identity server's data is transferred seamlessly to SimpleIdServer, ensuring minimal disruption and a smooth transition.
