xenserver

I have a XenServer 5.6 Free setup with 5 VMs (Windows and Linux) using about 1.5TB of directly attached storage.

Because our virtualisation needs have grown a bit, we currently are preparing a faster XenServer 6.0 Free machine with more RAM and a more storage. Again, directly attached disks.

How can I migrate the VMs between XenServer machines?

I don't need to keep the machines up and running during migration, but using VM export and import would definitely take too long.

Would making a VM with the same configuration on new host and dd'ing the LVM volume over network be the only quick and least painful solution? Are there any "gotchas" I should look out for when doing something like this? The old machine has an AMD Phenom II, the new has Intel Xeon E5 CPUs.
