I think it's a matter of "just wait" but I thought I'd check in here. My term vSphere licenses will expire tomorrow. I got these licenses last year from VMware... they came "bundled" with my Horizon licenses. We have a cluster (VCSA and four hosts) dedicated to our Horizon environment. We have a completely separate cluster (and licensing) for our "server" environment.
We renewed our Horizon agreement in April. We have already obtained the new Horizon license key from Omnissa and have entered it into our Horizon Administrator. All is good with Horizon proper. What I don't have yet are new licenses for vSphere (vCenter Server and the hosts). The two articles below (both from Omnissa) are applicable. One states that the vSphere license will still be included. The other describes the process of obtaining licenses, but also states that basically the license migration process is still in the works.
VMware Horizon combined offerings with vSphere and vSAN will continue post divestiture (14804)
Important Information Regarding Horizon Licensing and vSphere Infrastructure Licensing for Horizon (6000014)
I think that my only option is trial/temporary licenses. I am trying to work through that process now. If you have any knowledge or wisdom about any of this I'd love to hear it.
Also: We have NVIDIA graphics adapters in our Horizon hosts.
EDIT: It was mentioned elsewhere that there is a 30-day grace period, but it is unclear whether this applies only to the Horizon-proper side of things or whether it also applies to the vSphere licenses as well. Here is a reference link for that.
UPDATE 6/20/24: I used the email address below (in the post marked as the solution), and they helped me to locate my licenses. All good now.
I have just sent an email to that address. Thanks in advance.
