Reinstalling Xpenology to apply a valid SN

[crookedview]

I've been running the same Xpenology instance since 5.something and it's been through several upgrades.  I also have a valid serial number that I'd like to apply to my system.  From my understanding, changing the serial number must be done with a reinstall of the system.  I have an extra Surveillance Station license that I'd like to use, but need to apply the valid serial number first.

 

I'm using Jun's 1.03b bootloader, and running DSM 6.2.3.  I tried changing the serial number and MAC addresses via the grub config file, but that doesn't seem to update whatever is necessary for Surveillance Station to accept a new license.  Maybe I Just need to reinstall the surveillance station package?

 

Has anyone successfully reinstalled DSM while maintaining data?  Fairly painless?  Additionally, has anyone applied a valid serial number using this method?
