Can collected data be moved from one Android device to another

we tried copying the instances folder from one device (data collectors) to another device (supervisors). We did it by

(1) downloading the same blank form from the aggregate server down to both the supervisors and the data collectors device
(2) We collected data in a form on the data collectors device-
(3) we then copied the instances folder from the data collectors device to the supervisors device - we did this by connecting both devices to a pc via USB and then copying the instances directory from one device to the other
(4) we disconnected both devices from the pc
(5) We went into ODK and tried to edit saved forms on the supervisors device - but the data file wasnt listed in the tool

Would you expect that to work - or is there some reason that copying these files over would not have them render in the supervisors device? Do you know anyone who has done something like this and it worked?

If you need to copy content from one device to the other, first ensure that
the two devices are running the same Android OS version. It is also
recommended that they be the same model device, as each manufacturer makes
their own customizations of the Android operating system.

Then, to transfer the data, you must zip up the entire /sdcard/odk/
directory, and move that as a unit over to the other device.

The statuses of the filled-in forms on the device are maintained in other
files in the directory. You cannot simply copy them from device-to-device.
