Are existing Windows 7 Boot Camp partitions wiped out if you update to Mojave?

My Mac could install Windows 7 with High Sierra but cannot with Mojave. I was wondering what would happen if I had it installed with High Sierra and then tries to do a regular update to Mojave. Would it stay? Would it refuse to upgrade to Mojave?

I just tried this on my Mac Mini

Windows 7 partition is preserved after upgrade to Mojave, and all Bootcamp/drivers, reaminl intact.

Windows partition even appears as "Startup" disk under OS X Preferences, but is removed from Bootcamp Control panel... Therefore the only way back into OS X is via the Startup manager at boot (Hold Option key at startup)

Apart from that, it works fine.

I just got a new MacMini and ran into this problem. I wanted to Bootcamp WHS 2011. Does anyone think I could go back to High Sierra and install Bootcamp?
