Hi Parnassus,
You may appy the Enterprise licenses on the Standard Trial version.
I would advise the following steps :
01. Please visit My Networking Portal and register your iMC Enterprise product there. (Refer this document : https://support.hpe.com/hpsc/doc/public/display?docId=mmr_kc-0117119)
02. Go with re-install HPE IMC 7.3 from scracth using the Enterprise Edition. There are few reasons for that, beginning with
- the installation package of the iMC Standard (JG747A) version may not be the same as the iMC Enterprise version (JG748A).
-When you say "ok" for that message you get there, you are applying an Enterprise License to an Standard installation (Which is still fine), however the iMC enterprise feature has to be installed on the standard installation here. The same is true in the reverse case.
-If the standard product is registered in the My Networking Portal, you can very well still transfer the licenses from the Old SN# to the New iMC Enterprise SN#, however you have to log a support case with the licensing team for the license transfer, I suppose. They would ask you for the registered E-Mail address, and they can transfer the licenses from the Existing iMC Std SN# to the new Enterprise one.
If these above steps alleviates your querry, please dont forget to give kudos!
Regards,
