2) We have already tried below steps.
2a) Customer has deleted old files from RE0 and RE1.
2b) Rebooted RE1

Sometimes even we can see there is disk Space available on the device even though upgrade is failing. Checksum Mismatch can cause this issue as well. It is advisable to delete the image and reupload the image on the RE.
