Firmware Upgrade from 11.5.x to 13.1.1.x

Hello Wai Mun,

I believe I have some answers for you questions below.

1) "Can I upgrade the vcmp guest firmware without upgrade the vcmp host firmware?"

Yes, it looks like you should be able to do that. It ultimately depends on the hardware platform and the version you are upgrading to. In your case I believe you can do that without issue. Please see the following article for more information.

2) "Do I need to re-activate the vcmp host license before install the firmware? As I know the license cannot be re-activate from the vcmp guest. (service check date: 20150330)"

Yes, you will need to re-activate the vCMP Host license first. This is because your current service check date is earlier than the license check date of the software version you are upgrading to. The following article explains this.

3) "If i need to re-activate the vcmp host license, will it cause any interruption to the all the vcmp guest?"

Yes, it will cause a brief disruption. The following article notes this.

"Important: Reactivating the vCMP host license will result in a temporary traffic interruption on the guest systems while the license is reactivated on the host system."
