The guide explains how to migration Identity Server to OpenIddict Guides.
The startup template will use `OpenIddict` as the auth server by default since version 6.x.
> From ABP Version `6.0`, the startup template uses openiddict as the auth server by default, If you're using a version `6.x` startup template, then you don't need to migrate.
We are not removing IDS packages and will continue to release new versions of IDS related Nuget/NPM packages. That means you won't have an issue while upgrading to v6.0 (when it is released). We will continue to fix bugs in our packages for a while. ABP 7.0 will be based on .NET 7. If IDS continue to work with .NET 7, we will continue to ship nuget packages for our IDS integration.
BTW, IDS itself is canceling support for the open source IDS in the end of this year. They are moved to Duende IDS you know. We won't migrate to Duende IDS.
