Upgrading Unreal Versions

PLEASE BACKUP YOUR PROJECT BEFORE PROCEEDING!

It is recommended you use version control and/or File/Zip Project before proceeding.

This guide contains a generic upgrade path. Some additional considerations may be taken depending on the size/project configuration.

Ensure your project is fully closed.

Delete any of these temporary files: Build, Binaries, DerivedDataCache, Saved, Intermediate.

Remove and replace any plugin in your Plugins folder (for example VRExpansionPlugin) with the plugin version that matches the engine.

Right click on the blue Unreal project icon -> Show more options -> Switch Unreal Version. Choose the appropriate version.

Launch project. The project may prompt to complete various things as needed. If the project fails, check your Saved folder for Logs.

You may need to update your path to your NDK below:

Edit -> Project Settings -> Android SDK

UNREAL 5.5 - Location of Android NDK: C:/Android/SDK/ndk/25.xxx

UNREAL 5.6 - Location of Android NDK: C:/Android/SDK/ndk/27.xxx
