beta on some devices but not all?

[coolbreeze2]

I want to install Mojave beta on my MBP and install iOS 12 beta on my iPhone X while keeping High Sierra on my iMac and keeping iOS 11 on my iPad. Does anyone know of any if this potential problems keeping files and purchased applications synched across devices?

I haven't testet iOS 12 this year. But I do use both Mojave and High Sierra. Actually two Macs with each.
So far none of them have had problems with syncing anything.

Ok Thanks! I just thought of another idea. On my iMac create a dual boot with High Sierra and Mojave. I could consider doing the same on my MBP but it's only 256GB while the iMac is a TB.
