Failed to restore chat data to new phone. What's up?

[masterton]

I help a friend to transfer chat data to new phone.
I copied the GBWhatsapp folder to the PC. Then connected the new phone to the PC.
I clicked on the "internal storage" drive. Then pasted the GBWhatsapp folder.

I installed the app. Opened it. Clicked on restore.
Error message: Can't find any backup in 'sdcard/GBWhatsapp'.

I inserted an sd card to the new phone. Then connected to the PC.
I clicked on the "sd card" drive. Then pasted the GBWhatsapp folder.
The same error message popped up.

What's up? Why didn't the app find any backup?
Please help. Thank you.
