UE Plugin Migration tool

Hey everyone,

A little context for those who aren’t aware.
I have created a Windows app that recompiles any UE *.uplugin file to any UE version of your choice (example from 4.27 to 5.3 and vice versa).
The app helps to simplify the process of migrating your plugins by doing the heavy lifting for you using a simple UI.
I’ve personally tested it by converting plugins from older UE4 versions to UE5.
Remember is not a flawless app and your mileage might vary, specially if the plugin has some engine dependencies that are exclusive to that version., but for most of the plugins works really well.
I’m happy to announce that the code and application binaries of the version 2.0 are available on my GitHub page.

Remember I have a tutorial posted on YouTube, the app works essentially the same as the one in the video, I only updated the UI to make it much more modern and easy to work with.

Any feedback is well received.
Enjoy!

Hey, thanks for this!

Have you had any luck going forward or backwards from 5.3? I can’t seem to get the .uasset files to show when I move from/to 5.3.

Also, I always get the ~“Plugin built with different engine” message every time I open the engine, even though a migration has been successful. Is there any way to stop that?

Thanks!

Hello
Thank you for this great app. I have successfully compiled Freetrack plugin for UE5.4, however when I tried to repeat the same process for UE5.3 it fails. Looking into the log file, I can’t identify what has gone wrong.
Can you please check my log file to se if you spot anything?
Thank you

Hi Cesar.
I started having issues after a few UE5.4 release updates… the tool keeps on failing even trying again with plugins I already successfully migrated before their official update was available. Is that a known issue for you? Any update planned anytime soon?
Thanks in advance.

Cheers!

Stumbled across this yesterday and it looks like it might be very useful however while attempting to migrate a plugin from 5.3 to 5.5 I am returned with this error:

Output directory for packaged plugin must be outside engine directory
(see C:\Users…\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_5.5\Log.txt for full exception trace)

Following the instructions but I cannot get it to build. Have also tried setting an alternative directory outside the engine directory as requested by the error yet still it will not build. Any info would be much appreciated, thank you!
