I want to migrate level from one UE project to another. So I have migrated all the assets (whole Content folder) together and everything went through, but level (map). When I tried for the second time I got this information (image1) ![image1](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/5/c/35c83e8e712e1c5d1cc315459224c99609a847a1.png) So it looks like the map should be in the main project, but it is not. Then I checked to make sure its there by creating new level with the same name, and here’s what I got (image2) ![image2](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/8/f/28fb694b3de62286518d6fd5072f27efa1e856a3.png) I want to note that both project are on UE5.5.4 version. Have you ever encountered something like this? All help is appreciated. Thanks! ---

Solved right here: > [@Map missing after migrate to another project](https://forums.unrealengine.com/t/map-missing-after-migrate-to-another-project/441736/2): > > It is possible that the map file became corrupted upon copying it. Have you tried manually copying the map to the other project location?
