You are correct… I just removed the server.target.cs file and the project converted without error, I could also now generate project files. The problem is as I suspected related to the dedicated server file, but why would this happen? this was not a problem with 4.7. EDIT: If you create a project in 4.7 with a dedicated server build configuration, are you able to replicate this issue on your end? > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline.
