I am looking to upgrade our small server from server 2008 rs to windows server 2012 essentials, however we are only using one server and do not have funds to run another.
I came into this job recently and there is no documentation or proof of purchase for the current OS, i have no idea if it is even genuine or not and this is making me concerned, i have made the boss aware of this situation and they have asked if i can sort it asap, we have a copy of windows server 2012 essentials that has been unused and i plan on upgrading the system to that, this would mean me wiping the current server OS and installing the new OS as i don't want any sort of license conflict if i run upgrade setup, however this then means i will have to start a fresh active directory and the client computers will have to change domain causing me the headache of having to setup each computer.
Can anyone recommend a route I could take to wipe the current server OS, replace with 2012 essentials, but keep the active directory domain services without using a secondary server to migrate it?
Or should I just bite the bullet and start fresh?
