I may have overlooked something, but if I want to install a business edition of OPNsense on a blank machine, I can only start at an image of the community edition that is older that the current BE, change repository and upgrade. As far as I can tell, there is currently only the 26.7 image available for download and that won't "upgrade" to 26.4. Instead, I get a message that there BE repository doesn't exist. Looks like a dead end to me.
I'm gonna run the CE for now, so I don't need an older installation image but I wanted to let anyone know.
You can find the business images here: https://opnsense-update.deciso.com/
