Appliances (Phone System 40) - Upgrade to v14?

Hello,

I am setting up a new Sangoma Phone System 40. Before I even get started, should I just go ahead and upgrade the distro to FreePBX 14? It came with 13. I don’t see any problems doing so, but I can’t find much info if Sangoma does different branches for their own appliances. This isn’t the PBXact product.

I know how to install from USB on 3rd party hardware, but am not clear on what the Sangoma hardware entails. Do I just make a USB and boot to it? I assume the distro has everything the appliance needs?

EDIT:
Looks like I could just follow this??

Thanks.
