I have a Mac Mini running Sonoma 14.5. I want to partition the HD and copy my entire Mojave machine onto the partition. Being that everything will now reside on Apple Silicon, will the Sonoma Mac Mini let me boot up from the Mojave partition, so I can then run all my old 32-bit apps?

Running an older system on a newer system partition - is it even possible?
