First log on your old system and decrypt your /home directory. Then attach a
removable storage device with enough space to hold your /home directory. We
assume that your removable storage is mounted at /media/username/mount_point,
which can be checked by using lsblk command. Make sure that directory is
writable.
Backup your former /home directory:
~ $ tar zcvf /media/username/mount_point/backup.tgz .
When finished, unmount the removable storage device before disconnecting it.
Then attach said storage device to your new computer. We assume that it is
mounted at the same mount point.
Restore your former /home directory (including configuration files):
~ $ tar zxvf /media/username/mount_point/backup.tgz
When finished, all your configuration files should be transferred to your new
system.
