Retrieving your OS X Server’s serial number if you’ve lost it.
If your OS X Server has died and you need to rebuild it, you may find that you haven’t kept good track of where your serial number is. Nathan Toups posted a solution for that in his Twitter feed.
To do this on a running system:
1. Log in with an admin account.
2. Open Terminal.
3. Type sudo cat /etc/systemserialnumbers/xsvr
Your OS X Server’s serial number and the registered name and organization should be displayed.
If you’re retrieving from backups, get the xsvr file from /etc/systemserialnumbers to retrieve the serial number.

did you notice that /etc/systemserialnumbers is gone in 10.8?
No, I hadn’t seen that. It makes sense though, there’s no serial number needed to install 10.8 Server.
