Documentation
README · ~18 min readMigrating from IdentityServer4 to Duende IdentityServer
Scope: IdentityServer4 only. This skill covers migrating from IdentityServer4 (v3.x and v4.x) to Duende IdentityServer. It does not cover migrating from IdentityServer3 (the older Thinktecture/
IdentityServer3NuGet package that ran on OWIN/Katana and .NET Framework). IdentityServer3 is a fundamentally different product with a different API surface, configuration model, and hosting stack. If you are on IdentityServer3, you must first port to IdentityServer4 on ASP.NET Core before using this guide.
When to Use This Skill
- Planning a migration from IdentityServer4 to Duende IdentityServer — running the migration analysis tool
- Upgrading a project from IdentityServer4 (v3.x or v4.x) to Duende IdentityServer v8
- Replacing IdentityServer4 NuGet packages with Duende equivalents
- Updating
IdentityServer4.*namespaces toDuende.IdentityServer.* - Migrating EF Core database schemas from IdentityServer4 to Duende IdentityServer
- Upgrading the .NET target framework from
netcoreapp3.1ornet5.0to a current LTS version - Resolving breaking API changes between IdentityServer4 and Duende IdentityServer
