How to upgrade


Recommended Posts



I'm running DSM 4.1 on my new HP N54L. It is working great. But i like to upgrade to 4.2 or 4.3. I downloaded the 4.2 PAT file, but when i want to upload in DSM i get error 21.

What can i do to make this work?




The original pat file from official site will not work. You need a new, modified set - image and pat file from one of the latest releases. Trantor's repack is a good choice.

Make a backup. Burn a new image to USB and reboot from it. Use Synology assistant to find server and update with new pat file. Restore configuration if it's lost.

Basically the same procedure as the new installatition less formatting and volume/RAID creation.
