MrLynn,
Easiest way to do this is to clone your existing configuation to the USB drive. Boto off the USB drive. Upgrade it to Mojave. Make it the boot drive and use it for a bit. I found minimal problems moving from High Sierra to Mojave. If you're concerned about losing the ability to use older apps, you're likely to have that happen if you go from High Sierra to, say, Catalina (which doesn't support 32-bit apps). High Sierra to Mojave? Likely minimal problems.
