cannot import backendless 3x zip into backendless 4x

Hello,

I exported my Backendless 3x app (see attachment), but I cannot import it into backendless 4.
The error text is : “Attached archive has no valid files for import.”
Can you please help me on this issue.

Thanks

Hi Peter,

how did you do the export operation? Looks like you just exported your app files, not the app itself.
Please follow next steps to do correct migration:
In app you want to export click “Copy your app to 4.0” green button at the top of page:
https://goo.gl/8OpnjJ
Then in opened popup choose version of your app you would like to export and click “Create migration archive for 4.0” button.

After that you will receive an email with zip in attachment and detailed instructions for further actions you will have to perform to migrate.

If you have any questions, do not hesitate to ask me here.

Regards,
Stanislaw

Yes, this worked.
Thanks a lot!
