Using Time Machine with different OS?
I'm planning to use Time Machine to transfer data from my late 2018 MacBook Air (Intel i5 chip) to a new MacBook Air (Apple M1 chip). My 2018 is currently running Mojave 10.14.6. The new MacBook Air has Big Sur 10.16. If I use my Time Machine back-up from my 2018 MBA to transfer all my content on to the new MBA will it also transfer the OS or is the software smart enough to only transfer the data but not the OS? Or, should I just be safe and install Big Sur on my 2018 MBA and then perform a Time Machine Back-up. Once that is complete, then use Time Machine to set up my new MBA. Thank you.
MacBook Air 13″, macOS 10.14
