Good! This is an advantage.@CaseySJ
All of them are standard 2.5 SSDs. I'm thinking to do an initial deployment on just 2 SSD (or may be 1 SSD and 1 HDD - we will see) to mirror my current setup. If everything works, I should be able to CCC both into one single NVME after thorough Mojave testing. Does that make sense?
I have never worked neither with NVMe nor with APFS and really want to take small steps in order not to mix everything together and be able to roll things back easily if I need to. Also, I did not make a final selection on the NVME, but still can move on and test Mojave. In the end of the day if everything works it will take me may be 15-20 min max to clone (CCC) everything to a single NMVE.
Because you are upgrading from High Sierra to Mojave, I don't think a Time Machine restore is the correct procedure. Mojave has additional security/sandbox implementations. Mojave may have different folder hierarchies. (Catalina takes this further and creates a new "data" volume automatically and mounts the system in a read-only volume.)
Therefore my recommendation goes like this:
- Format SSD4 as APFS and connect to the system. Label it "Data" or "Mojave Data" or anything appropriate.
- An external USB 3 2.5" SSD enclosure really helps.
- Perform fresh installation of Mojave 10.14.5 SSD3.
- Make a backup of SSD3 when post-installation is completed.
- When Mojave is fully installed, open System Preferences --> Users & Groups, unlock the lower left padlock, right-click on your user name, select Advanced and change the home directory to SSD4.
- Connect both SSD1 (High Sierra) and SSD3 (Mojave) at the same time (external USB 3 enclosures really help).
- Use Migration Assistant to move Apps and Data to the new system.
- Migration Assistant should be able to resolve the locations of the old and new home directories by itself.
