Hi, we have customer want to upgrade the DCE basic appliance version from 7.2 to 7.6; customer have just renewed the software contract and have downloaded the v7.6 image from us. the information have received is that it can boot from flash disk with v7.6 image but can't complete the boot process and fail over to the existing v7.2 image; can you please let us know if we can restore the DCE directly from v7.2 to v7.6; or should go by upgrade plan like go through series of intermediate version then finally arrive to v7.6? thank you!
Erdenedulam, please provide more detail info on upgrade process and boot failure; thank you!

I'm not sure what it is you're doing here but it seems that you've just put the ISO file on the USB key (I'm assuming this is NOT a DVD drive). This is not how the USB key should be put on a USB stick. If you look at the page from which the ISO was downloaded, you should see a download for a key generator utility and the command to run it:
Open a command prompt to the temporary directory and run mkDCExpertRestoreUsbKey.bat <iso image filename>.

Ok, so assuming you've properly created the USB key and the restore at least begins, I am still not sure where it is hanging.
I would suggest trying the following:
1: connect that USB key to one of the rear USB ports
2: Run an MD5 checksum on the download to verify it is good
3: Get a USB DVD drive and burn the ISO to a DVD, restore with that.
