Error Migrate proyect Unreal 5

Hola, espero que puedan ayudarme.
Migre un proyecto de Unreal 4.27 a Unreal 5 y me faltan muchos asset con el siguiente error.
Hi, I hope you can help me.
I migrated a project from Unreal 4.27 to Unreal 5 and I am missing many assets with the following error.

Helicop_Idle.uasset has newer custom version of FortniteMain

xxxxx.uasset has newer custom version of Release

there are 200 assets with the same problem.

Hi, well, I think I know what the problem was. Unreal 4.27 was not compatible with unreal 5 early access. You always have to read the docs, ha!

I have run into this problem myself. Try adding the problem assets to a UE5 project but select version 4.26 for the assets you are adding.

Longer Explanation:
I found some assets were giving me this error, and I don’t even understand why FortniteMain would even have a version number. Anyway, I created a new UE5 project and added those problem assets to it and told the launcher I wanted to add 4.27 assets to my UE5 project. Same problem came up. So I deleted the project created another UE5 project, and this time I added these assets as 4.26 and now I don’t have an error and I can see those assets in UE5. I have then migrated those assets back into my converted project.

Thanks for answering my question.
I see a lot of work to find compatibility right now.
I’ll wait for the final version of Unreal 5 to come out so I can migrate it.

For anyone in the future who may be searching, I was able to solve this problem by using the script here.

Absolutely, you must follow this pipeline, hope this picture is useful to you guys. Early access only allows files from UE4.26
En teoria no puedes pasar de 4.26 a 5 directamente
Tampoco de 4.27 a early access.
