HP Virtual Connect firmware upgrade ?

People,

I'm  in the process of upgrading my ESXi hosts to vSphere 6,  so I'm stuck in this confusion of what is the best way to perform the existing Virtual Connect firmware update to the latest version v4.45 described in this document http://vibsdepot.hp.com/hpq/recipes/HPE-VMware-Recipe.pdf on page 7

Here's my current environment:

HP VC Flex-10 Enet Module on Bay 1 & 2
Part Number: 455880-B21
Spare Part Number: 456095-001
Firmware Version: 4.01

HP B-series 8/24c SAN Switch BladeSystem c-Class on Bay 5 & 6
Part Number: AJ821A
Spare Part Number: 489865-001
Firmware Version: N/A

However there is big risk of outage and configuration lost involved as stated in this http://h20565.www2.hpe.com/hpsc/doc/public/display?sp4ts.oid=3794423&docId=emr_na-c04422904

So I need your help of what are the safest steps to be taken without causing outage issue in my current VMware environment ?

Thanks.

There will be outage. do you have 2 switches in blade shelf to configure them to use side that you are not updating? It is not risk of outage, connection will be off while new firmware boots for 5 minutes, and you must be very lucky if it migrates old configuration. Been there with cisco blade switches.

I recommend you schedule an outage window as your switch go offline and migration may take longer.

@gheist: yes there are two Virtual Connect blades in the HP c7000 blade enclosure.

@Mohammed Khawaja: Let me know if you have successfully upgraded the firmware to VC v4.45 before, I want to know if there is any issue during or after the upgrade process ?

As I mentioned virtual connect restarts. It may take 5s or 50s.
Just re-check your network connections that each of VC blades can support all tenant networking alone.
