Unable to migrate to 4.7 preview

Hey guys,

I attempted to migrate my project to 4.7 preview and when attempting to save I get the following error message:

This map is using externally
referenced packages which won’t be
found when in a game and all
references will be broken. Perform a
map check for more details.

Would you like to continue?

Mapcheck shows that every single asset is externally referenced. I’ve attempted to migrate the assets from the original project as well as direct copy. Upon performing a map check, still, every single actor in the maps are apparently externally referenced.

Everything seems to work in the editor, so at this point I don’t see any detriment to the upgrade to the 4.7 preview. Not sure if there are any steps outlined to address this or if it is known issue; this is the only similar issue and none of what he tried worked in my case.

I haven’t seen too many posts on this issue, so I’m not sure how wide-spread it is, making me think I may need to configure something to get this to work…?

Please let me know if there is further info I can provide for this.

OK - well, almost immediately after posting this, I retried making a direct copy of my project, and it seems to work now -

The only thing I did differently was to open the project with 4.6 by accident, I forgot to switch engines, then I compiled for 4.7 and re-started and it seems to be fine now.

Here’s the steps I took (albeit inadvertently) in case anyone else runs into a similar situation:

1 - Copy the project to new location
2 - Build the project in its current engine
3 - Change the engine
4 - Rebuild and run

Well - sorry about spamming the hub!

See the comment to the issue above - issue self-resolved.

Hey thx dude. Looks like the Launcher isn’t working so well. I cloned it, then converted it. Manually copying the project seemed to resolve this issue as you recommended. Thanks again.

Awesome bro - glad it helped!

A better and faster solution than the already mentioned one is to:

simply rename the folder, run the project, rename folder to previous name again, done.

I had the Same issue and this fixed it thx:
