SID depends on time zone also!
Sadly until today I got no answer if there are other Informations it depends on.
Once Avaya support desk wanted me to reinstall a virtual primary server. I asked if they guarantee that I get the same SID again so that licences will still work and from that point the support guy didn't want to give me a GO. So no one knows for sure? I think I will try it in our lab. Install, configure, delete the machine. Install and configure a new one on another host with same IPs and host names and time zone.
Two hours of work but useful to know what's possible or not.
Reinstall from scratch and wait one or two days for a license swap because you get a new SID is not an option. Especially in bigger Serber Edition solutions.
