The Products tab gives you an overview of the products you can license, with all the license keys grouped accordingly. After the keys have been added, we can go ahead and use them to license the corresponding VMware products. Figure 10 - A listing of all the available license keys on vCenter Server. The new keys should be listed alongside the previous ones. Press Finish on the last screen not shown and then verify that the new keys have in fact been added. This screen also provides details about the product expiry and capacity relevant to each key. This makes it easier to identify which key is being assigned to what. The keys are obfuscated for obvious reasons! On the next screen, you can name the license keys. Select the Licenses tab on the Licenses screen and click on the green arrow button to add the new license keys. After you load vSphere Web client, click on Licensing from the Home screen. Adding license keys to vCenter is the first step.

If on the other hand, the features unlocked by the current key do not suffice, you will need to replace the current key with a new one that does. If the managed ESXi hosts have already been licensed, you can simply stick with the currently assigned license when adding hosts to vCenter Server as shown in Fig. A separate license is required for vCenter.

You will need to license vCenter itself and, optionally, any ESXi hosts it is managing. This applies to both the Windows and appliance versions. Removing will list all the information associated with the key as per the previous screenshot. The output is piped into grep so that only the product key is listed. Since there can only be one license assigned at any time, the last one entered is picked up by default. If for any reason you need to remove a license, you can do so by clicking on the Remove License button. If it is valid, press Assign License once more to apply it. Click on Check License to verify the key. Click on the Assign license button and type in the designated license key. Click on Manage and select the Licensing tab. The host must not be managed by vCenter Server - hence the term standalone - when using these methods. There are two ways to apply license keys on ESXi.

From a recently held conversation, I learned that licensing VMware products can be a tad confusing to some.
