Migrating with partition

Migration Assistant is used to copy one's Home folder from an older computer to a new one. It is not a backup utility so it isn't going to copy from non-bootable partitions. If you do want those other three partitions to be copied to the new computer, then you will need to make new partitions on the new computer.

If you make the new partitions equal to or slightly larger than the old partitions, then you can use Disk Utility to clone them. In this case, "equal" means the same number of blocks. The default blocksize is 512 bytes. This clones one partition at a time:

Clone using Restore Option of Disk Utility

1. Open Disk Utility in the Utilities' folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the Disk Utility main window.
4. Select the destination volume from the left side list and drag it to the Destination entry field.
5. Select the source volume from the left side list and drag it to the Source entry field.
6. Double-check you got it right, then click on the Restore button.

Destination means new partition. Source means old partition.

Well, it depends. If the OS builds are different then you will have to use Migration Assistant for the bootable system. What is on the other three partitions? I can't really give you a definitive reply without knowing that.

I can tell you that cloning a partition is faster than migrating one unless you have a small Home folder, no third-party apps and support files, and a basic system preferences file.

I'm about to migrate from a 2014 13" MacBook Pro to a new touch bar 2016 model.

The issue is that I have 4 partitions that I want to move as well. Is there a way to do this automatically or first of all I should make the partitions on the new mac manually and after that to backup from a time machine?

I must specify that I have installed MacOs High Sierra on both laptops.

Thank you for all your responses.

Kindly regards.
