I would like to disassociate the vSphere 5 Essentials license key assigned to the host so that I can use it on a new server. I am under the impression that the license key will have to be removed from the ADAM's Database. I am not sure how this is accomplished and haven't been able to find another KB article that explains the process. I do not need to retain any of the hosts configured on the current server. I just need to free up the license to use on a new install. If there is any clarification needed please let me know.
If I understand your question correctly, you wish to replace an existing ESXi host and you won't be making any changes to vCenter.
What I forgot to mention is that my server has 64GB of RAM which is why I had to purchase a licenesed version. All I am trying to do is free up my license so that I can use it on a new server. I don't need anything associated with the old server. None of the hosts or anything.
I just want to do a fresh install on my new server and use use my purchased license. I may not have used a correct eval license because when I attmepted to replace the licenesed version with it, I was given a message that I couldn't because I was over the 32GB limit. Image attached.
Support was able to resolve this issue by assignin g me a temporary license key for vSphere 5 Essentials. I applied that temporary key and was able to free up my licensed key. Initially they has eluded that they couldn't help becuase I had only purchased the license and no support but once they understood what I was trying to accomplish they reached out and helped me. Hopefully this helps someone if they run into a similar issue.
