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.
