Have you tried using tar to create a tarball, then copying the tarball to the other server and untaring it? Newer OS's have a --compress option, which might help.

However you copy it, you may want to copy over the directories in different threads, hence you get some level of parallel. You can do a find to get the folder names, then split up the list into separate files and have a different process migrate each folder.

virt-tar-in(1)						      Virtualization Support						    virt-tar-in(1)

NAME
virt-tar-in - Unpack a tarball into a virtual machine disk image. SYNOPSIS
virt-tar-in -a disk.img data.tar /destination virt-tar-in -d domain data.tar /destination zcat data.tar.gz | virt-tar-in -d domain - /destination WARNING
Using "virt-tar-in" on live virtual machines can be dangerous, potentially causing disk corruption. The virtual machine must be shut down before you use this command. DESCRIPTION
"virt-tar-in" unpacks an uncompressed tarball into a virtual machine disk image or named libvirt domain. The first parameter is the tar file. Use "-" to read the tar file from standard input. The second parameter is the absolute target directory to unpack into. EXAMPLES
Upload a home directory to a guest: virt-tar-in -d MyGuest homes.tar /home JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-in" command. For anything more complex than a trivial copy, you are probably better off using guestfish directly. OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options. SEE ALSO
guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-make-fs(1), virt-tar-out(1), http://libguestfs.org/. AUTHORS
