Making the product available for older versions

Hello,
what is the correct way to make our product compatible with older versions of engine, if it’s already been approved for the newest one?

I have uploaded a project compatible with 5.4, but I had a request to make it compatible with older, 5.1 version too. I’ve added a new version via “file update”, which is made in 5.0 and I ticked support for 5.0-5.3. The update was declined and they sent me the following response:

How should I do it properly to support all UE5 versions?

Older engine versions can’t show or open files from newer engine versions. You need to create the project from scratch in an older version, then select it as compatible. Also note that if you check multiple engine versions, they must all compile without errors then, otherwise make a special build just for the version that has errors.

If you need to have assets in an older version format and you don’t want to recreate them you can use my plugin Asset Downgrader to downgrade to your desired version (down to 4.26).
