No it is better that everything comes over all at one time

It depends upon if you created a partition table, partitions and filesystems on
the drive.
I create the drive layout on the drive then rsync the old drive to the new
drive.
Then I fixup the PARTUUID in the /etc/fstab and boot loader.
If I am using Archlinux or my own custom build os I have a blank /etc/fstab and
/etc/hosts
cat /etc/fstab
# Static information about the filesystems.
# See fstab(5) for details.
# <file system> <dir> <type> <options> <dump> <pass>
cat /etc/hosts
# Static table lookup for hostnames.
# See hosts(5) for details.
