Miniraze and Waverazor are not patch compatible. They are different. Granted, you can find most of the 'components' of Miniraze in Waverazor, but Miniraze has some hardwired connections that do not exist in Waverazor. In summary, no, you cannot develop patches in one for the other.
The idea behind these products is that they are different ways of approaching MOK's synthesis:
Miniraze is a dialed-in topography using many of Waverazor's features, but it is designed to be fast to tweak and program sounds, using a familiar Minimoog-style subtractive UI. The deeper Filter and EFX settings are dialed in under-the-hood for the most common use cases. Miniraze also has the ability to send OSC3 to Filter FM, it also has the ability to use OSC2/3 as a RingMath Carrier/Modulator pair (though I do have plans to bring these features to Waverazor this year, but it will be in a less-hardwired way).
Waverazor gives you access to everything (in the Editor), you need to work for your patches, but you have a ton of flexibility in what you can do, and there are a lot of features in Waverazor that simply do not exist in Miniraze. Waverazor has way more Filters and EFX to choose from, with access to all of the deep and nerdy parameters of those components.
I hope that helps explain how these two products are different. As we use the same oscillator in both products, I can see how it might appear that these are different flavors of the same thing, and in some scenarios they are very similar and in others they aren't so much. If you want quick access to a lot of sounds and sound banks from a lot of great programmers, Miniraze is the way to go. If you enjoy the deep dive and creating sounds nobody has ever heard, Waverazor is your tool. And depending on your inspiration at any given time, they can both sit alongside each other in the toolbox.
