Question about Resizing Azure FTDv

[hurricane05]

I currently have a few Production FTDv deployed in Azure and looking to resize them. I do see the option where I can resize when the FTD is off. My question is can I resize the existing FTD or do I have to build new virtual FTDs with the new size? I wasn't sure if resizing current virtual FTD in Azure would cause any issues.

Thx in advance for any assistance given.

I never tried this on cloud hence I found this link it might be helpful for you.
on my personal experience I have tried adding network card on vmware vftd it did not see it when powered on. until I found this link vmware 

Caution

You cannot add more virtual interfaces to the virtual machine and then have the threat defense virtual automatically recognize them. Adding interfaces to a virtual machine requires that you completely wipe out the threat defense virtual configuration. The only part of the configuration that remains intact is the management address and gateway settings.

Hi Sheraz,
Thx for the feedback. My plan wasn't to add additional NICs but rather update the Cores/Memory.
